Thousands? Maybe not, but hundreds? Yeah, for my freelancer/contracting gigs, it's easily worth $200/month to be able to say "How come X is like that and what change lead to Y being Z?", wait 20 minutes and then get an answer that jumpstarts understanding a completely new codebase. If AI/LLMs never evolved beyond their current skills and usefulness, I'd still be happy to pay $200/month for this.

However, I don't know a single developer who pays "thousands of dollars a month", not sure how you'd end up like that.
