As a former AI skeptic I get it and still get it.

But now other people's code is just a starting point for me forking an app to do exactly what I want it to - it's inspiration because code is cheap.

Of course for larger projects we will still need solid components underlying them, but what you're really talking about is just maturity - it's very easy to produce a lot of output now but you can't replace actual history or having more then exactly 1 maintainer.
