I hear this from people extolling the virtue of AI a lot, but I have a very hard time believing it. I certainly wouldn't describe 90% of my coding work as boilerplate or API glue. If you're dealing with that volume of boilerplate/glue, isn't it incumbent upon you to try and find a way to remove that? Certainly sometimes it isn't feasible, but that seems like the exception encountered by people working on giant codebases with a very large number of contributors.
I don't think the work I do is innovative or even novel, but it is nuanced in a way I've seen Claude struggle with.
