Claude with the 4.7 model is getting pretty good.

there is a significant learning curve to using AI well. learning to stay skeptical and keep your brain on, developing an intuition of how much free reign to give it, writing ironclad specs and design docs and keeping them updated, making work easy to inspect, the tone you use talking to it, using one agent to critique another's work, etc.

basically, AI will produce slop if left unattended. but it's not really its fault.. it's a process failing, like not supervising the interns. using AI the Right Way(tm) is a mental workout, quite a bit slower, but extremely rewarding (ime.)
