I mean if it were anyone else, yeah I might agree, but I think Salvatore is being genuine here (and have seen Claude do a similarly surprising job fixing ops issues).
I don't think so. I think he's clearly abusing language (saying "Claude Code migrated the stufff", rather than "I migrated the stuff after using Claude to help write boilerplate, then I went on double-checking it, testing it, and then running it")
On the other hand he has totally drunk the Kool-AI(d).
