Most of the folks that are talking about this are the ones who work independently and work on greenfield projects (especially tooling related). The cost of making a mistake there is so low. I've used it similarly and it's absolutely amazing. Though I still use a mix of agents and code myself in my regular 9-5 job.

I've yet to see examples of folks using this in a team of 4+ folks working together in a production env with users, and just using AI for their regular development.

Claude code creator only using claude code doesn't count. That's more like dog-fooding.
