Android 12 system UI: splash screens + stretch overscroll
All apps get auto-generated splash screens and a new stretch overscroll animation, system-wide.
Both shipped with Android 12 in Oct 2021 across all apps.
Android 12 with Material You
Biggest design refresh in Android history; wallpaper-based dynamic theming, redesigned widgets, new animations and privacy features.
Released to AOSP on Oct 4, 2021 and Pixel on Oct 19, 2021, broadly on time. Material You spread to other OEMs starting with Galaxy S22 in Feb 2022 and is the basis of every Android release since.
Android Earthquake Alerts global expansion
Expand Android's crowdsourced earthquake detection and alerts from California/Greece/New Zealand to additional high-risk countries worldwide.
Rolled out broadly through 2021–2024 across Turkey, the Philippines, Kazakhstan, the Pacific, much of Latin America, and most of Asia. Now available in dozens of countries. One of I/O 2021's clearest unambiguous wins.
Steady global expansion delivered the original promise.
Android Privacy Dashboard + camera/mic indicators
Single dashboard showing what apps accessed location/camera/mic and when; always-on indicators when sensors are active.
Shipped in Android 12 in Oct 2021; remains a core part of Android.
Android Private Compute Core
On-device, network-isolated partition for AI features like Live Caption, Now Playing, and Smart Reply; open-source and inspectable.
Shipped with Android 12 (Oct 2021). Has been extended every release and is now the basis for many on-device AI features in modern Pixels.
Android Studio Arctic Fox + Apple Silicon support
New Arctic Fox version with Compose tooling; native Apple Silicon (M1) build of Android Studio.
Arctic Fox stable shipped July 28, 2021. Apple Silicon canary builds arrived in 2021, native stable later in 2022. Routine releases since.
Flutter 2.2
Cross-platform Flutter 2.2 stable with null safety by default, web service-worker caching, deferred Android components, iOS shader precompile.
Shipped at I/O 2021 as promised. Flutter has continued shipping (3.x) and is widely used; remains Google's flagship cross-platform UI toolkit.
Google Maps eco-friendly routing
Routes optimized for lowest fuel consumption when ETA is similar; promised to cut emissions equivalent to 200k+ cars/year.
Launched in the US on Android/iOS in October 2021. Expanded to Canada and Europe in 2022, with broader EV-aware variations since. The feature still exists today as a default Maps option.
Google Photos Locked Folder
Passcode-protected folder for sensitive photos, starting on Pixel and 'coming to more Android devices'.
Launched on Pixel in May/June 2021. Rolled out to all Android devices in early 2022 and to iOS in 2023. Now a standard Google Photos feature.
Google Workspace for everyone (consumer + Individual tier)
Open Workspace to all 3 billion Google account holders; add a new paid 'Workspace Individual' tier for freelancers/SMBs; rename Rooms to Spaces.
Shipped on June 14, 2021. Spaces went GA. Workspace Individual launched in mid-2021 in select markets. The branding consolidation has stuck.
Jetpack Compose 1.0
Stable 1.0 of Android's modern declarative UI toolkit by July 2021.
Released 1.0 on July 28, 2021 as promised. Has become the recommended UI toolkit for Android and powers a large fraction of new Android apps.
Phone Hub on Chrome OS
Tight Android-Chromebook integration: phone notifications, recent Chrome tabs, hotspot toggle, silence/locate from Chromebook shelf.
Started rolling out in Feb–March 2021 and went broadly available later in 2021. Has been expanded with photo streaming, app streaming (Pixel-only), and notification mirroring.
Shopping Graph + Shopify partnership
AI-built Shopping Graph spanning 24B product listings; 1.7M Shopify merchants gain one-click distribution across Search, Maps, Images, Lens and YouTube.
Shopify integration shipped in 2021 and expanded. Shopping Graph is still a real Google product and underpins shopping experiences in Search and Lens.
Smart Canvas in Google Workspace
Major reinvention of Workspace collaboration: smart chips, @-mentions of files/people/meetings, pageless docs, integrated Meet, checklists, templates.
Rolled out broadly from late 2021 through 2022 with smart chips, pageless mode, checklists, table templates, and timeline views. By Oct 2022, smart-canvas usage exceeded comment usage in Docs. Continues to be expanded; among the most successful items of I/O 2021.
Tensor chip / Pixel 6 teases
Heavy I/O 2021 ML demos that signposted the upcoming custom Google Tensor SoC and a more ambitious Pixel.
Tensor was officially announced Aug 2, 2021, and shipped in Pixel 6 on Oct 28, 2021. Google has stayed on Tensor through Tensor G5 (Pixel 10, 2025) and beyond.
TPU v4 Pods
Next-gen TPU with 4,096-chip pods delivering >1 exaflops of ML compute, ~2x faster than TPU v3; coming to Google Cloud customers.
Used internally from 2020 onward; reached Google Cloud customers in 2022 (preview) and broader availability shortly after. Powered training of PaLM and other models. Succeeded by TPU v5e/v5p, Trillium (v6), Ironwood (v7).
Cloud GA came roughly 12 months after I/O announcement — within reasonable range.
Vertex AI
Unified managed ML platform consolidating AutoML and AI Platform; promised ~80% fewer lines of code to train a model.
Launched the day of the keynote (May 18, 2021) as GA. Has become Google Cloud's flagship ML/AI platform and now hosts Gemini, Model Garden, Agent Builder, etc.
Shipped late 2
Android Digital Car Key (UWB/NFC)
Pixel and Galaxy phones to unlock and start compatible BMWs (and other cars) via UWB/NFC; phone-as-key.
BMW NFC Digital Key launched on Android in late 2021. UWB-based 'Digital Key Plus' for Android (the I/O demo) didn't arrive on BMW until April 2023 — almost 2 years after promised — and only on Pixel 7 Pro and select Samsung devices. Five years on, support remains BMW-only with very few other automakers onboard.
UWB 'magic walk-up' version slipped ~2 years; remains very narrow in OEM coverage.
Built-in Android TV remote in Android phones
Replace Android TV's separate remote app with a system-level remote in every Android phone.
Built-in TV remote shipped in Google's Quick Settings in 2022, accessible via system widget. Works with Google TV/Android TV. Standalone remote app was eventually phased out. Shipped roughly 12 months after announcement.
Slightly past the 6-month bar; functional but quietly delivered.
Scaled back 13
AI tuberculosis screening from chest X-rays
Deep-learning model matching radiologists at flagging TB on chest X-rays, intended for high-burden countries.
Research published 2021–2022. Real-world deployments in India and other LMICs through 2023–2024 (incl. published validation studies). Never productized as a Google product; mostly lives as research papers and partner-led pilots. No major public progress in 2025–2026.
Stalled as a Google product line; survives only as research/partner work. Borderline vapor on the Google product side.
Carbon-aware computing (24/7 carbon-free by 2030)
Shift compute workloads to data centers and times of day with the cleanest energy; full 24/7 carbon-free energy by 2030.
Carbon-aware scheduling for batch workloads shipped in 2021–2022 — that piece is real. But Google's overall emissions have RISEN sharply due to AI demand (up ~48% from 2019 baseline as of 2024 sustainability report), and the 24/7 CFE-by-2030 goal looks essentially unreachable. The headline promise is functionally broken even though work continues.
Carbon-aware scheduling shipped; 2030 net-zero/CFE goal is on track to be missed by a wide margin.
Cross-device APIs / 'devices work better together'
Better Android-Chromebook-watch-TV-car integration: spatial audio handoff, instant tethering, unified setup, etc.
Partial. Spatial audio with head tracking arrived 2022 on Pixel Buds Pro. Quick Share/Nearby Share unification with Samsung happened in 2024. A formal Cross device SDK launched 2023. Overall the 'just works' vision Google sold lagged Apple ecosystem by years and most consumer-facing handoff moments still don't exist.
Detailed Street Maps + safer routing
Up to 50 highlights per trip ('busy area' alerts, safer-routing variant choosing routes with lower hard-braking probability) and Detailed Street Maps with sidewalks/crosswalks in 50 more cities.
Safer routing shipped in late 2021 on Android/iOS in the US but never expanded internationally as promised. Detailed Street Maps reached fewer cities than the announced '50 more,' and the feature is rarely surfaced. Quietly present but under-scoped.
Both sub-features shipped but at materially smaller scope than announced.
Fast Pair to cars and Wear OS
Fast Pair (one-tap Bluetooth pairing) extended to cars from BMW/Ford and Wear OS watches.
Fast Pair for cars launched with BMW and select Ford vehicles in 2022; Wear OS pairing shipped on Pixel Watch (2022) and Galaxy Watch 5. OEM coverage remains a fraction of what was implied at I/O 2021 — most cars still don't support it.
Shipped late and at narrower OEM coverage than promised.
Google Photos Cinematic Moments
ML stitches together near-identical photos and fills in the gap to create cinematic, moving 'memory' clips.
Rolled out as part of Memories in mid-2021. Exists but quietly de-emphasized; never became the headline Photos feature Google teased and surfaces rarely in the modern Memories experience.
Shipped but materially less prominent than promised; effectively a minor Memories sub-feature now.
Google Photos Little Patterns
ML surfaces patterns across your library (e.g. the same orange backpack worldwide) as a new Memories type.
Quietly rolled out in summer 2021. Still technically present in Memories but rarely surfaces and never became a notable user-facing feature; overshadowed by other Photos features and effectively abandoned as a marketed feature.
Shipped but at much smaller scope/visibility than announced.
LaMDA (Language Model for Dialogue Applications)
Breakthrough conversation AI demoed with Pluto and paper airplane personas; framed as the future of natural, open-ended dialogue across Google products.
LaMDA powered a closed AI Test Kitchen app in 2022, then was used as the initial engine for Bard (Feb 2023). Bard was upgraded to PaLM 2 by May 2023 and rebranded to Gemini in Feb 2024. The original LaMDA pitch — open-ended persona-driven dialogue (Pluto, paper airplane) — never shipped as a public product; Bard 1.0 was a stripped-down chatbot that explicitly refused that kind of persona play. Brand and original promise both effectively dead.
Technology lineage lives on in Gemini, but the original LaMDA promise (free persona conversation) was abandoned. Also produced the Blake Lemoine 'sentience' controversy in June 2022.
Live View indoor AR navigation (airports, malls, transit)
Expand Live View AR walking directions to indoor venues like airports, malls, and transit hubs in multiple cities.
Initial rollout to a handful of US malls in 2021, expanded to Tokyo, Zurich, and large European cities by 2022. Coverage remains spotty and Live View as a whole has been steadily de-emphasized in favor of Immersive View. Quietly being scaled back in 2024–2026.
Nest Hub (2nd gen) Sleep Sensing with Soli
Radar-based contactless sleep tracking on the new $99 Nest Hub, building on Project Soli.
Shipped March 2021. Sleep Sensing was free in 2021, then planned to move behind a Fitbit Premium paywall — that paywall was delayed multiple times and ultimately the free preview was extended indefinitely. Nest Hub line has since stagnated with no successor; the product is on a slow death march.
Announced pre-I/O 2021 but heavily featured during I/O sessions. Product line effectively dormant.
Project Starline
Photorealistic 3D 'magic window' video booth, demoed as the future of remote presence; planned trial deployments in Google offices and partner workplaces.
Stayed an internal prototype for four years. At I/O 2025, rebranded as 'Google Beam'; the HP Dimension launched at $24,999 with limited rollout to enterprise customers only. The 2021 pitch was a future of consumer/workplace presence — what shipped is a niche enterprise videoconferencing rig at a price point that excludes virtually everyone. Materially less than promised in scope, reach, and accessibility.
Four years from demo to a niche, ultra-expensive enterprise product. Rebranded as Beam but the original 'magic window for everyone' promise is unmet.
Project Taara wireless optical links
Post-Loon free-space optical 'fiber-without-the-fiber' links shown at I/O 2021 as the next phase of connectivity in hard-to-reach areas, including a high-profile Congo River crossing.
The Congo crossing was real but Taara remained an Alphabet X experiment for years. Spun out of Alphabet in 2025 as an independent company with backing from Series X Capital, after limited commercial deployments. The original 'global connectivity' framing remains far away.
Spinout in 2025 confirms it was not scaling within Alphabet at the originally implied pace.
Unified Wear OS (with Samsung Tizen merge)
Google and Samsung jointly rebuilding Wear OS, merging best of Tizen and Wear OS for a faster, longer-battery smartwatch platform across all watches.
Wear OS 3 shipped on Galaxy Watch 4 in Aug 2021 — but as a Samsung exclusive at launch. Rollout to existing watches (Fossil, TicWatch, Mobvoi) was massively delayed by 1.5–2+ years; many older models never received the update at all. The 'all watches benefit' promise was effectively broken; existing-Wear-OS-customer migration path was abandoned.
Existing Wear OS customers were largely left behind. The merger benefited new Samsung/Pixel hardware, not the broader Wear OS ecosystem as promised.
In progress 1
Quantum AI Campus + million-qubit goal by 2029
New Santa Barbara campus with fab + data center; goal of a useful, error-corrected, million-qubit quantum computer by end of decade.
Campus operational. Willow chip (Dec 2024) demonstrated below-threshold error correction with 105 qubits — five years from now, Google would need to scale by ~4 orders of magnitude to hit a million qubits. The 2029 deadline is widely considered unrealistic; public progress continues but the specific million-qubit-by-2029 promise is essentially aspirational marketing.
Willow is real public progress, so not vapor. But the headline 2029 million-qubit number is extremely unlikely to be met at promised scope.
Vapor 2
AR translation glasses concept (in-keynote tease)
I/O 2021 closing reel and demos suggested real-time translation/AR overlays as part of Google's near-future hardware ambitions (precursor to the Project Iris/AR-glasses pitch).
Real AR translation glasses prototype was shown at I/O 2022, but Project Iris was shut down in 2023 and Google pivoted to providing Android XR for partners (Samsung's Project Moohan, 2025). No Google-branded consumer translation AR glasses have shipped.
Closest live successor is Android XR on partner hardware — not the original first-party promise.
MUM (Multitask Unified Model)
1000x more powerful than BERT; would understand text, images and 75 languages and power dramatic new Search experiences.
Google has explicitly stated MUM is 'not used for general ranking.' Used only narrowly for COVID-19 vaccine info, About This Result, and multisearch in Google Lens. The marquee 1000x-BERT product never materialized; the multilingual cross-modal search vision was effectively abandoned and overtaken by LLMs/Gemini and AI Overviews. The MUM brand has largely disappeared from Google communications.
A handful of MUM-adjacent launches (multisearch, About This Result) shipped, but the headline promise of MUM as a search ranking/understanding breakthrough never happened.
Killed 2
AI Dermatology Assist Tool
Web app to help identify skin, hair, and nail conditions, launching first as a CE-marked Class I medical device in the EU later in 2021.
Launched in limited EU markets in 2021 with CE Class I marking. Never came to the US (FDA path never opened). Google quietly shut down the standalone DermAssist app and shifted the use case into Google Lens skin-condition lookups, which are explicitly NOT medical-grade. Dormant as a Google Health product line with no public updates in years.
Standalone DermAssist effectively defunct; functionality reduced to non-medical Lens lookup.
Chrome auto password change (Duplex on the Web)
Chrome would use Duplex to automatically reset compromised passwords across major sites with a single tap.
Launched on Chrome Android in late 2021 for a small set of sites; expanded slightly in 2022. Never reached the broad coverage promised. Duplex on the Web itself was killed in December 2022, gutting the feature. Unavailable today.
Duplex on the Web shutdown effectively ended the feature.
