It's a good point, my first thought is that the AI can replace surface level software easily, but the structure and context it needs to "recreate" git in a accurated and at a professional level would consume trillions of tokens, and even then the chance that it is usable from the get go it's low.

The vibe coders can replace SPA, python scripts, small and low context things. Everything else it is outside the scope. It’s more of a testing tool: you give it snippets, input/output examples, and instructions on how and where it should be used.

PD: My personal take on SaaS, is that is about to go bullish.
