Flappy Bird is a well-known game by now, and it's simple enough that lots of people have produced tutorials online about how to write it. My guess is that it's mostly regurgitating code out of its training corpus.<p>It'd only be impressive if you asked it to create a novel game of similar complexity and it was also able to do that successfully.
Bout to throw in the towel on this whole software developer career thing. Guess I'll go be a plumber or something. Maybe have GPT tutor me there too while I'm at an apprentice level.
GPT4 is impressive but all this is hype. It recreated it because some one else created it previously. Its not like it created a new game from scratch !
