What if he ships a game and a programming language by the end of next year? In 2 years? In 5 years?

I think if he ships a game and a programming language in any of those timeframes I will be very impressed. I also think it is likely.

Looks like his Sokoban game releases 2026- he just uploaded a trailer: https://m.youtube.com/watch?v=OIxuGF6CwnU&pp=2AEAkAIB

I'd consider JAI shipped, it's just not publicly available. There are hundreds (maybe thousands?) of developers in the beta at this point. Next time you build a new programming language, 3D game engine, and ship a game, lemme know how long it takes.

Casey's done both Handmade Hero, and Performance Aware Programming. Some of the best programming educational content available, in my opinion.

Also .. so what?
