Undergrads vs AI: who codes faster?
Using Antigravity for Statistical Physics in JavaScript
Antigravity builds a magnet demo, devs ask: worth the switch
TLDR: Google’s Antigravity IDE with Gemini 3 produced a simple magnet simulation in about an hour. Comments split between tool fatigue and doubts about quality—some praise the page-reading plugin, others say an undergrad could do it faster—fueling the bigger question: switch tools now or stick with what works?
Google’s new Antigravity coding tool (born from Windsurf) teamed with Gemini 3 Pro to whip up a JavaScript visualization of the classic Ising model—think tiny magnets deciding whether to align—in about an hour. The author loved the Chrome extension that lets the AI “read” the page structure, but shrugged at the flashy task lists. Cue the crowd: half dazzled, half exhausted. One commenter basically sighed, “another week, another playground,” confessing they’re stuck between VS Code + Claude and Colab + Gemini, and begging for the dev-tool hype train to hit the brakes.
Then the spice: a skeptic dropped the line of the day—this wasn’t impressive and “an undergrad could do it in an hour.” Suddenly it’s AI vs. freshmen in a speedrun. Memes popped: “Ising? More like Easy-ing,” “Antigravity can’t lift expectations,” and “Cursor will ship this by Friday,” nodding to the prediction that Cursor will clone the best bits. Fans praised the browser page-reading feature as the real hero; critics called the rest “demo theater.” The vibe? A tug-of-war between switch-tool FOMO and quality fatigue—is Antigravity the new home base or just another shiny tab you’ll forget by Monday
Key Points
- •The author shifted their benchmark for testing new LLMs to JavaScript-based statistical physics visualizations.
- •Google’s Antigravity IDE with Gemini 3 Pro produced an Ising model visualization in about an hour.
- •A Chrome extension for DOM retrieval significantly aided the coding and visualization process.
- •The author reports previously achieving decent results with OpenAI and Anthropic models.
- •Antigravity is described as essentially Windsurf, with UI elements like subtasks and intermediate steps.
