Even if it takes me a month to get us to fix (likely a week tbh), then it took us 3 months to build.

A mere 2x productivity improvement sounds like something you could achieve by introducing new tools that are predictable (i.e.: Not AI).

Perhaps. 2x is still 2x. And new tools still need to be vetted and learned.

It's strange that the goalpost seems to have moved from "AI is net negative to productivity" to "only 2x improvement isn't worth it"
