I highly doubt "pumping out bespoke apps all day" is possible yet besides 100% boilerplate, and when possible then no good for any other purpose than enshittifiying the web, and at that point not profitable because everyone can do it.

I use AI daily as a senior coder for search and docs, and when used for prototyping you still need to be a senior coder to go from say 60% boilerplate to 100% finished app/site/whatever unless it's incredibly simple.
