Is there definitive proof of long term productivity gains with no detriment to defects, future velocity, etc?

If so I’d say you’re irresponsible at best to put this much trust in a tool that’s been around for a few months (at the current level). Absolutely encourage experimentation, but there’s a trillion dollar marketing hype machine in overdrive right now. Your job is to remind people of that.
