Yeah that’s been my experience. The generators are shockingly good. But they don’t get it all the way, and then you are left looking at a mountain of code you don’t understand. And by the time you do, you could have just built it yourself.
SWEs that do not have (or develop) this skill (to fill-in the 10% that doesn’t work and fully understand the 90% that works and very, very quickly) will be plumbers in a few years if not earlier.
