I suppose, yes, AI was like a kickstart. But the point is - he didn't just stick to AI, he realized that in terms of skill and fulfillment it's a no-go direction. Because you neither learn anything, nor create anything yourself.

I feel the same way. But this is a new economy now, software is cheap, and regarding the skill and fulfillment you derive writing it yourself, to quote Chris Farley: "that and a nickel will get you a nice hot cup of JACK SQUAT!!!"
