Not to slip too far into analogy, but that argument feels a bit like a horse-drawn carriage operator saying he can't wait to pick up all of the stranded car operators when their mechanical contraptions break down on the side of the road. But what happened instead was the creation of a brand new job: the mechanic.
I don't have a crystal ball and I can't predict the actual future. But I can see the list of potential futures and I can assign likelihoods to them. And among the potential futures is one where the need for humans to fix the problems created by poor AI coding agents dwindles as the industry completely reshapes itself.
Both can be true. There were probably a significant number of stranded motorists that were rescued by horse-powered conveyance. And eventually cars got more convenient and reliable.
I just wouldn't want to be responsible for servicing a guarantee about the reliability of early cars.
And I'll feel no sense of vindication if I do get that support case. I will probably just sigh and feel a little more tired.
