GPT-6 Astra just rebuilt an entire Steam fishing game from watching gameplay footage once.

We're talking full mechanics:
→ Cast, hook, fight, reel, land loop
→ Bending rod physics + dynamic fishing line
→ Fish collision + flopping behavior
→ 6 species (including Big Barry)
→ Upgrades, currency, journal, saves
→ You can throw, punt, and grill the fish

Video in. Playable game out.

This isn't incremental. AI is now reverse-engineering entire game systems from raw footage. No code. No prompts. Just watch and rebuild.

If you're not paying attention to what foundation models can do in 2025, you're already behind.
