> I don't think they're a net gain if you're a skilled senior

I've had Claude Code running a /loop for the last week driving down complex crashing bugs in a prototype compiler entirely unilaterally. I occasionally glance over.

A few of those crashing test cases were ones I've spent more than a week trying to track down myself. I have 30 years of experience of doing this.

It's worked 24/7.

So far it has fixed over 500 of them.

Will there be technical debt? Yes. But nothing that remotely compares to the cost I'd have incurred of fixing all of those myself.

It is hard to reconcile those gains without thinking that if people are saying these are not a net gain, they haven't really tried learning how to get the full benefit. If you sit and watch a model work and keep intervening all the time, then sure, they're not going to be a net gain.
