Productivity really means nothing across companies and the software industry. So we code faster, but honestly problem I see is companies ask us to code stupid or worthless things in many cases.

CTO is rewriting company platform (by himself with AI) and is convinced it's 100x productivity. But when you step back and look at the broader picture, he's rewriting what something like Rails, .NET, or Spring gave us 15-20 years ago? It's just in languages and code styles he is (only) familiar with. That's not 100x for the business, sorry...
