> what can I do at Google I/O ?
▸ Thought Process
  Considering User Intent
  Depending on your developer focus, you can tailor your Google I/O experience into a specialized
  learning journey. Here is a breakdown of the core developer pathways and exactly what you can do
  in each:
  ──────
  ### 🚀 Journey 1: The AI & Agent Developer

  If you want to build intelligent, autonomous, and highly context-aware systems:

  • Master Gemini 3.5: Explore the latest APIs to leverage massive context windows, multimodal
  inputs (text, image, audio, video), and enhanced coding capabilities.
  • Develop with Antigravity 2.0: Learn how to use this new agent-first development platform to
  build autonomous, goal-oriented systems that can run multi-step reasoning workflows directly in
  production.
  • Integrate Firebase Genkit: Dive into sessions showing how to build, test, and run AI-powered
  features using TypeScript/JavaScript or Go in a developer-friendly framework.

  ### 📱 Journey 2: The Mobile & Spatial Developer

  If you build apps for phones, tablets, foldables, and wear:

  • Design for Android XR: Start building immersive, spatial experiences for upcoming smart
  glasses and headsets using your existing knowledge of Kotlin and Jetpack Compose.
  • Adopt Kotlin Multiplatform (KMP): Learn best practices for sharing business logic, networking,
  and data storage between iOS and Android.
  • Implement On-Device AI: Watch deep dives on using Gemini Nano locally on Android devices to
  handle tasks like smart replies, summarization, and translation without requiring network calls.

  ### 🌐 Journey 3: The Modern Web Developer

  If you are dedicated to building fast, beautiful, and accessible web applications:

  • Build with Built-in Browser AI: Discover how to utilize Chrome’s new built-in AI APIs
  (leveraging local on-device models) directly within your web apps.
  • Leverage Modern CSS & Web Performance: Explore upcoming browser APIs, new layout models, and
  how to track modern Core Web Vitals to deliver ultra-premium web experiences.
  • Rely on Baseline: Learn how the "Baseline" initiative makes it easy to identify which modern
  web features are universally supported across Chrome, Safari, Firefox, and Edge.

  ### ☁️ Journey 4: The Cloud & Backend Engineer

  If you manage deployment, scalability, and developer workflows:

  • Deploy with Firebase App Hosting: Try out the next-generation hosting platform that
  automatically detects, builds, and deploys server-rendered frameworks like Next.js, Angular, and
  Nuxt.
  • Scale AI Workloads on GKE: Learn how to optimize Kubernetes for high-performance AI inference
  and custom model fine-tuning.
  • Utilize Vertex AI Agent Builder: Build enterprise-grade agents grounded in private data
  sources with zero machine-learning experience required.

  ### How to Take Action Now

  1. Bookmark your path: Go to the Google I/O Session Catalog https://io.google/2026/program/ and
  filter by your chosen pathway.
  2. Access Codelabs: Go to io.google/codelabs https://io.google to access step-by-step
  programming tutorials for all these new technologies.
  3. Engage with Google Experts: Visit the digital developer forums or official Discord channels
  to ask questions and discuss lessons with the engineers who built these products.
