Android I/O 2018

Adaptive Battery

Shipped Shipped 2018-08
Promised

A DeepMind-powered feature that learns which apps you actually use and throttles the rest to extend battery life.

Reality

Shipped in Android 9 Pie in August 2018 and is still on by default across Android. Independent reviewers found gains modest but real; the feature has quietly evolved across subsequent Android releases without fanfare.

One of the few I/O 2018 features that delivered at promised scope and is still actively maintained.

AI for Social Good + $25M Impact Challenge

Shipped Shipped 2019-05
Promised

A program funneling Google AI research toward humanitarian problems (flood forecasting, whale tracking) plus a $25M Google.org grant pool for nonprofits.

Reality

The $25M was awarded to 20 grantees in May 2019. Flood Hub launched to the public in 2022 and expanded to 80+ countries. Most of the original initiatives still exist in some form.

Money distributed and programs continue.

AI-powered diabetic retinopathy screening with Verily

Shipped Shipped 2019-02
Promised

Google/Verily showcased a deep-learning model that screens eye fundus photos for diabetic retinopathy, headed to clinics in India and Thailand.

Reality

Received CE mark, deployed at Aravind Eye Hospital (India) in 2019 and rolled out further in Thailand. By 2023 the algorithm had screened hundreds of thousands of patients; Verily continues to expand it.

Delivered at promised scope and still actively expanding.

Developer I/O 2018

Android App Bundle (AAB)

Shipped Shipped 2018-05
Promised

A new publishing format that lets Play deliver only the code/resources each device needs, shrinking download sizes.

Reality

Shipped at I/O 2018 and became mandatory for new apps on Google Play in August 2021. Over 1 million apps and the majority of the top 1,000 had adopted AAB by 2021; still the standard in 2026.

One of I/O 2018's only unambiguous wins.

Developer I/O 2018

Android Jetpack

Shipped Shipped 2018-09
Promised

A re-organized suite of libraries (AndroidX, WorkManager, Navigation, Paging, plus the existing Architecture Components) to standardize modern Android development.

Reality

AndroidX 1.0 shipped in September 2018 and Jetpack has only grown since — Compose, the modern UI toolkit, became part of Jetpack and is now the default for new Android apps in 2026.

Delivered at promised scope and still actively maintained.

Android I/O 2018

Android P (Android 9 Pie)

Shipped Shipped 2018-08
Promised

The next Android release, billed as 'AI at the core of the OS,' with adaptive features and a new gesture navigation pill replacing the three-button bar.

Reality

Released to Pixel devices on August 6, 2018 — roughly on schedule. The pill gesture nav was widely criticized as a half-measure and was replaced in Android 10 (2019) by a swipe-based system closer to iOS. The OS itself shipped at promised scope.

The OS shipped on time; the specific pill-shaped gesture nav was killed one year later, but the release as a whole delivered.

Other I/O 2018

Gboard Morse code input

Shipped Shipped 2018-07
Promised

Morse code as an accessibility input method in Gboard, developed with Tania Finlayson.

Reality

Beta on Android the day of the keynote, stable on Android and iOS by July 2018. Still available.

Niche but actually delivered and maintained.

Google Lens — real-time results, Smart Text Selection, Style Match

Shipped Shipped 2018-05
Promised

Lens upgrades: results overlaid live on the viewfinder, Smart Text Selection to copy real-world text, and Style Match to find clothes/decor visually.

Reality

Real-time results and Smart Text Selection shipped in late May 2018 as promised. Style Match shipped but the visual shopping use case migrated into Google Shopping and (later) Circle to Search, where it's been substantially more successful than the original Lens framing.

Delivered roughly on time; evolved into Circle to Search.

Other I/O 2018

Google One (paid storage rebrand)

Shipped Shipped 2018-08
Promised

Announced in May 2018 as a rebrand/relaunch of Google Drive paid storage plans, with family sharing, member perks, and a unified subscription brand.

Reality

Rolled out in the US in August 2018 and globally through 2019. Has since absorbed Google's consumer VPN (launched 2020, then killed June 2024) and become the host for the AI Premium / Gemini Advanced tier in 2024–2026. Brand survives; some perks were quietly dropped.

Delivered and grown into Google's main consumer-subscription wrapper, though the included VPN was killed in 2024.

Photos I/O 2018

Google Photos Suggested Actions

Shipped Shipped 2018-07
Promised

AI suggestions inline on photos: share with the person it recognized, brighten, rotate, archive.

Reality

Shipped through 2018 and 2019 as promised; suggestions still appear on photos and have been quietly subsumed by Magic Editor / Gemini-powered editing features in 2024–2026.

Delivered at promised scope; still actively used.

Workspace I/O 2018

Google Tasks (relaunch)

Shipped Shipped 2018-04
Promised

A revived Tasks product with a dedicated Android/iOS app, integrated with the redesigned Gmail and Calendar.

Reality

Standalone apps shipped in April 2018; Tasks became a G Suite core service on June 28, 2018. Still available and has gained recurring tasks and starred lists; Reminders were merged into Tasks in 2022–2023.

Delivered at promised scope and consolidated rather than fragmented.

Developer I/O 2018

Material Theming (Material Design 2)

Shipped Shipped 2018-05
Promised

A refreshed Material Design system with a Theme Editor (Sketch plugin) and customizable color/typography/shape tokens.

Reality

Shipped at I/O 2018 and rolled out across Google's apps through 2018–2019. Material You/Material 3 succeeded it in 2021 and Material 3 Expressive in 2025 — the I/O 2018 system itself is obsolete but evolved into its successors rather than being killed.

Superseded but not killed — natural design-system evolution.

Workspace I/O 2018

Smart Compose in Gmail

Shipped Shipped 2018-05
Promised

ML-powered phrase autocompletion that suggests the rest of your sentence as you type an email — pitched as a free, universal Gmail feature.

Reality

Rolled out to consumer Gmail in May 2018 and to G Suite in September 2018. Later expanded to Docs (2019), Android (2019), more languages. The free Smart Compose still works in Gmail today; the more ambitious next-gen 'Help me write' lives behind paid Gemini for Workspace tiers, but the original feature delivered at promised scope.

One of the few unambiguous shipped-at-promised-scope wins from I/O 2018.

Cloud I/O 2018

TPU 3.0

Shipped Shipped 2018-05
Promised

Google's third-generation Tensor Processing Unit, 8x the performance of TPU v2 per pod, requiring liquid cooling for the first time.

Reality

Delivered to Google Cloud customers in 2018–2019. TPU v3 was followed by v4 (2021), v5 (2023), Trillium/v6 (2024), and Ironwood/v7 (2025).

Shipped at promised scope and still the backbone of Google's AI infrastructure roadmap.

Other I/O 2018

Wireless Android Auto support

Shipped Shipped 2018-08
Promised

Wireless Android Auto would expand beyond Pixel/Nexus to any phone running Android 9.

Reality

Shipped with Android 9 Pie; expanded to all Android 11+ phones in 2020. The separate phone-screen Android Auto app was killed in 2022 in favor of Assistant Driving Mode (which itself was shut down in 2024). The car-display wireless variant is the surviving part.

The specific wireless-Android-Auto promise (head-unit casting) shipped and is widely used; adjacent products died.

Shipped late 1

Web I/O 2018

Linux apps on Chrome OS (Crostini)

Shipped late Shipped 2019-02
Promised

Native Linux app support on Chrome OS for Android and web developers.

Reality

Reached dev channel in fall 2018 and stable in Chrome OS 72 (February 2019). Still supported in 2026.

Stable launched ~9 months after I/O announcement — just inside the 'shipped' window but late enough to flag.

Scaled back 14

Android I/O 2018

App Actions

Scaled back Shipped 2018-08Killed 2023-06
Promised

A system that lets apps surface deep-link 'actions' (e.g., 'Call Mom on Duo') across the launcher, Search, Assistant, and Play Store based on context.

Reality

Shipped with Android 9 Pie's actions.xml schema, but adoption was thin and the Google Search integration promised in the keynote never materialized. Google moved developers to Android Shortcuts; the original actions.xml is officially deprecated and most Assistant built-in intents were sunset in 2023.

actions.xml deprecated; surviving as a thin wrapper over Android Shortcuts. The Search integration promise was never kept.

Assistant I/O 2018

Continued Conversation

Scaled back Shipped 2018-06
Promised

Talk to Assistant naturally without re-saying 'Hey Google' for follow-up questions.

Reality

Rolled out to Google Home and Nest in June 2018. Still works on legacy Assistant surfaces, but Google Assistant is being replaced by Gemini through 2026 and the feature's natural successor is Gemini Live's continuous conversation mode.

Lives in a product being sunset; capability is migrating to Gemini Live but the original product home is dying.

Android I/O 2018

Digital Wellbeing (Dashboard, App Timer, Wind Down)

Scaled back Shipped 2018-09
Promised

Tools to help users see and limit time on their phone: a usage Dashboard, per-app timers, Wind Down grayscale at night, and improved Do Not Disturb.

Reality

Launched in beta with Android 9 Pie in fall 2018 and rolled out broadly in 2019. Features still nominally exist but have received essentially no meaningful updates in years; 2026 coverage explicitly noted Google has let the suite stagnate while pivoting attention to Gemini.

Shipped on time but unambiguously de-emphasized — the marquee anti-addiction framing is gone.

Assistant I/O 2018

Google Assistant Custom Routines

Scaled back Shipped 2018-07
Promised

User-created scheduled and triggered routines (e.g., 'Good Morning' to turn on lights, read the news, and start a commute).

Reality

Shipped in summer 2018. Routines remain functional and the concept lives on in Google Home Automations, but the Assistant-branded version is being absorbed into Gemini / Google Home as Assistant is sunset.

Capability survives under different umbrellas; the Assistant-Routines branding is on its way out.

Google Duplex

Scaled back Shipped 2018-11Killed 2022-12
Promised

An AI that calls businesses on your behalf, demoed booking a hair-salon appointment and restaurant reservation with shockingly natural speech (including 'um' and 'mm-hmm'). Pichai framed it as a glimpse at a future general-purpose conversational AI.

Reality

Launched on Pixel phones in November 2018, narrowly limited to restaurant reservations in a handful of US cities. A 'Duplex on the Web' expansion in 2019 was killed in December 2022. The voice-calling sliver still technically exists for restaurant bookings but never became anything close to the general-purpose conversational agent the demo implied — it's now a footnote next to Gemini.

The viral demo was effectively orphaned; Duplex on the Web was killed Dec 2022 and the rest has been swallowed by Gemini's voice features.

Google Lens built into OEM camera apps

Scaled back Shipped 2018-05
Promised

Lens would be integrated into the camera apps of 10 phone makers — LG, Motorola, Xiaomi, Sony, Nokia, Transsion, TCL, OnePlus, BQ, Asus.

Reality

Integrations shipped through 2018, but most OEMs either replaced Lens with their own visual search or quietly removed the shortcut. Lens itself is now part of the Google app and the Pixel camera; the headline cross-OEM camera integration largely evaporated.

The 10-OEM cross-pollination story didn't last.

Maps I/O 2018

Google Maps AR walking directions (Live View)

Scaled back Shipped 2019-08
Promised

AR walking navigation overlaying arrows on the camera view, powered by a new Visual Positioning System (VPS). Demo included flying animated butterflies as guides.

Reality

Beta launched August 2019 — over a year late — as 'Live View' for Pixel and select ARCore/ARKit devices. Broader rollout came in 2020. The flying butterflies never shipped. In 2024 Google began winding down some Live View features.

Late, lost the whimsical guide-character demo entirely, and is now being de-emphasized — scope materially less than promised.

Other I/O 2018

Google News redesign (AI-powered)

Scaled back Shipped 2018-05
Promised

A relaunched Google News app combining elements of Newsstand and YouTube, with AI-driven 'For You,' 'Newscasts' and 'Full Coverage' sections.

Reality

Shipped on schedule in May 2018 and replaced the old Google Play Newsstand. The app still exists but has been overshadowed by Google Discover and AI Overviews; 'Newscasts' as a distinct feature quietly faded. The ambitious AI-meets-journalism framing is gone.

Core app survives but is a husk of the I/O 2018 vision.

Other I/O 2018

Google Pay (Android Pay + Google Wallet merger)

Scaled back Shipped 2018-02Killed 2024-06
Promised

Google folded Android Pay and Google Wallet into a single 'Google Pay' brand in early 2018, with I/O 2018 expanding it to ticketing and airline boarding passes.

Reality

Rebrand shipped in February 2018. But in 2022 Google revived 'Google Wallet' as the pass-storage app while keeping Google Pay for P2P — partially undoing the consolidation. By 2024 Google Pay's standalone US app was discontinued in favor of Wallet, effectively reversing the I/O 2018 merger.

The consolidation pitched at I/O 2018 was unwound — Wallet absorbed Pay's functions in the US and the standalone Pay app was killed.

Photos I/O 2018

Google Photos black-and-white Colorize

Scaled back Shipped 2021-06
Promised

An AI feature that automatically colorizes old black-and-white photos — demoed live on stage as a near-term consumer feature.

Reality

Promised at I/O 2018 with no date. David Lieb confirmed at I/O 2019 it was 'still coming.' A limited beta finally surfaced in October 2019; broader availability didn't arrive until 2021–2022 and even then required a Google One subscription. Eventually folded into Magic Editor / Gemini photo tools.

Three-plus years late and ended up paywalled behind Google One — far less than the I/O 2018 demo implied.

Assistant I/O 2018

Multilingual Google Assistant

Scaled back Shipped 2018-08
Promised

Assistant would understand two languages at once on the same device — initially English/French/German/Spanish/Italian/Japanese.

Reality

Rolled out in August 2018 with English/French/German first, expanded later. Still works on Assistant, but the product is being replaced by Gemini, which handles multilingual interactions natively.

Feature delivered but rides the Assistant ship into the Gemini sunset.

Assistant I/O 2018

Multiple Actions

Scaled back Shipped 2018-05
Promised

Chain commands in one sentence: 'Turn off the lights and play jazz.'

Reality

Shipped the day of the keynote. Still technically works on Assistant, but the entire Assistant product is being replaced by Gemini, whose multi-step reasoning makes this 2018 feature a quaint footnote.

Feature still works but lives in a product Google is actively killing.

Assistant I/O 2018

Six new Google Assistant voices (WaveNet)

Scaled back Shipped 2018-05
Promised

Six new Assistant voices built with DeepMind's WaveNet for more human-sounding speech.

Reality

Shipped on day one of I/O 2018. The WaveNet voice stack is still used, but the Google Assistant product itself is being supplanted by Gemini through 2025–2026, with explicit sunset messaging on Android and Nest devices. The voices technically still work; the product they live in is on death row.

Feature shipped, but it lives inside a product Google is actively winding down for Gemini.

Other I/O 2018

Waymo commercial self-driving service (Phoenix, late 2018)

Scaled back Shipped 2018-12
Promised

Waymo would launch the world's first commercial robotaxi service in Phoenix later in 2018 — the I/O 2018 framing strongly implied a true driverless service.

Reality

Waymo One launched December 5, 2018 — just barely on time — but with safety drivers behind the wheel and limited to early-rider members. Truly driverless public rides didn't open broadly until 2020; meaningful expansion (Phoenix airport, SF, LA, Austin) came in 2024–2025.

Demo implied immediate full driverless service; reality was safety-driver chaperoned rides for an invite-only group. Capability eventually arrived but years later.

Rebranded 4

AR/VR I/O 2018

ARCore Cloud Anchors

Rebranded Shipped 2018-05Killed 2023-08
Promised

Shared AR experiences across Android and iOS by anchoring virtual objects to cloud-synced positions in the real world.

Reality

Shipped in ARCore 1.2 in May 2018. The original Cloud Anchor API cloud endpoint was deprecated and shut down on August 31, 2023, replaced by a newer ARCore API. Functionality continues under a new name.

API moved; capability preserved.

Developer I/O 2018

ML Kit for Firebase

Rebranded Shipped 2018-05Killed 2020-06
Promised

An on-device ML SDK packaged inside Firebase for text, image, face, barcode and label recognition.

Reality

Shipped in May 2018 as a Firebase beta, but in June 2020 Google split it: on-device APIs were spun out as the standalone ML Kit SDK, and the Firebase-branded on-device APIs were deprecated. The capability survived; the Firebase branding did not.

Capability preserved under new name — clean rebrand.

Developer I/O 2018

TensorFlow Lite for mobile/edge

Rebranded Shipped 2018-05Killed 2024-09
Promised

Heavily featured at I/O 2018 as the production-ready way to run ML models on phones and edge devices, with new optimizations and partner integrations.

Reality

Shipped and matured into the standard mobile ML runtime for Android. In 2024 Google rebranded TensorFlow Lite as 'LiteRT' under the broader AI Edge umbrella, signaling a pivot away from TF-centric branding toward a multi-framework runtime (including JAX/PyTorch).

Capability preserved as LiteRT; TF-Lite branding effectively retired.

Hardware I/O 2018

Wear OS (rebrand of Android Wear)

Rebranded Shipped 2018-03
Promised

Android Wear was renamed Wear OS in March 2018 and got new I/O attention with a darker, more battery-friendly UI.

Reality

Shipped as a rebrand. Wear OS stagnated badly until the 2021 Samsung partnership produced Wear OS 3 on the Galaxy Watch 4. Now it powers Pixel Watch and Galaxy Watch lines, though the I/O 2018 era of the platform was effectively a three-year fallow period.

Three lost years between rebrand and Samsung relaunch; capability ultimately preserved.

Vapor 1

Android I/O 2018

Slices

Vapor Killed 2021-12
Promised

Interactive snippets of app UI that would appear inline inside Google Search and Assistant — e.g., a Lyft Slice showing ride prices right in Search.

Reality

The androidx.slice APIs technically shipped, but the marquee Google Search integration — the entire point of the announcement — was quietly paused around 2021 and never returned. By Android 13 the feature was effectively invisible to users; the App Actions integration was marked deprecated.

APIs exist as a developer ghost-town. The promised Search integration never reached users — textbook vapor at promised scope.

Killed 7

Assistant I/O 2018

Actions on Google / third-party Conversational Actions investment

Killed Shipped 2018-05Killed 2023-06
Promised

I/O 2018 hyped a thriving third-party 'Actions' ecosystem on Assistant — apps, games, and businesses building voice experiences, with new tooling and discovery surfaces.

Reality

The third-party Conversational Actions program was fully shut down on June 13, 2023. Google forcibly migrated remaining developers to App Actions / Android Shortcuts, and many businesses' voice apps simply ceased to exist.

Entire third-party voice ecosystem Google spent years promoting was unceremoniously killed.

Other I/O 2018

Android Things 1.0

Killed Shipped 2018-05Killed 2022-01
Promised

A stripped-down Android-based OS for IoT devices, finally reaching 1.0 with partner devices from JBL, Lenovo and LG.

Reality

Within nine months (February 2019) Google had narrowed scope to smart speakers/displays only. In December 2020 Google announced shutdown; the console stopped accepting new devices Jan 5, 2021 and stopped distributing updates Jan 5, 2022.

Classic killed-by-Google trajectory.

Maps I/O 2018

Google Maps 'For You' tab

Killed Shipped 2018-06Killed 2022-12
Promised

A personalized recommendations tab in Maps surfacing new restaurants and places matching your taste.

Reality

Rolled out in June 2018 in five countries and expanded to 130+ markets in December 2018. The tab was quietly removed/merged in late 2022 as Google replaced the bottom-nav with 'Explore' and 'You'.

Shipped, then unceremoniously folded into other surfaces.

Assistant I/O 2018

John Legend celebrity voice for Assistant

Killed Shipped 2019-04Killed 2020-03
Promised

John Legend would lend his voice to Google Assistant — the first 'celebrity cameo' voice.

Reality

Shipped April 2019 — almost a year late — and was removed March 23, 2020. Other cameo voices (Issa Rae) followed similar short lifespans. The whole 'cameo voice' concept was abandoned.

Always pitched as time-limited, but the splashy I/O demo glossed over that. Dead within a year.

Assistant I/O 2018

Pretty Please

Killed Shipped 2018-11
Promised

An optional family mode that thanks kids for saying 'please' to Assistant.

Reality

Rolled out in November 2018 for Family Link accounts. Nominally still available but Google has barely mentioned it since 2019; many smart-display surfaces no longer expose the toggle. With Assistant being replaced by Gemini, the feature's death is essentially scheduled.

De facto abandoned and on track to disappear with the broader Assistant sunset.

AR/VR I/O 2018

Sceneform

Killed Shipped 2018-05Killed 2020-08
Promised

A 3D rendering library for ARCore so Java developers could build AR without learning OpenGL.

Reality

Shipped May 2018. In August 2020 Google announced Sceneform would no longer receive new features; the open-source repo was archived. Replaced by community fork SceneView.

Abandoned to the community.

Hardware I/O 2018

Third-party Smart Displays with Google Assistant

Killed Shipped 2018-07Killed 2023-04
Promised

Showcased third-party Assistant-powered smart displays from Lenovo, JBL, LG, and Sony — a category to rival Amazon's Echo Show.

Reality

Lenovo Smart Display launched July 2018, JBL Link View and LG WK9 followed. Google stopped major development on the underlying OS in February 2019, shifted to its own Nest Hub line, and in April 2023 stopped issuing software updates to those third-party displays entirely.

Third-party displays effectively abandoned; even Google's own Nest Hub line faces a murky future as Assistant is replaced by Gemini.
