AI software can't do what you're claiming.
And AI software research started officially at Dartmouth in 1956 but the formal reasoning research behind it started in the 1200's with the work of Ramon Lull.
If that's too much of a stretch for you - let's go back up to 1956, when Newell, Simon and Shaw wrote Logic Theorist, the first program designed to reason.
But hey, why not ignore how long AI software has been in development and just agree it's more than "a year".
What game are you thinking about? Pong? Space Invaders?
Space Invaders took one person, the great Tomohiro Nishikado 1 year to make. That's 2,000 hours or maybe he worked overtime! Make it 3,000 hours.
Can AI software program a copy of Space Invaders in a few seconds? I don't know - I haven't seen it done, but that's your claim. I did look it up - and yes, ChatGPT could generate a version but it took far longer than "seconds".
But you know what - ChatGPT could do it because Space Invaders already exists.
AI can make games in seconds that took entire companies hundreds of thousands of hours to make… and it’s, what, a year old?
