That's irrelevant in this context, because it's not "get the humans to make a working product OR get the AI to make a working product"
The problem is you may pay $20K for gibberish, then try a second time, fail again, and then hire humans.
Coincidentally yes, I am aware, my last contract was building out a SCADA module the AI failed to develop at the company that contracted me.
I'm using that money to finance a new software company, and so far, AI hasn't been much help getting us off the ground.
Edit: oh yeah, and on top of paying Claude to fuck it up, you still have to also pay the salary of the guy arguing with Claude.
