A major problem is backwards compatibility. There is so much infrastructure that would break if they wanted to redo portions of code in a more correct fashion. They have a massive variety of systems, and they’re all integrated. Any time they want to do something, they’re scared of something breaking. This time, AI is finding a shit ton of the vulnerabilities that are in these systems, and at least in part fixing them. It’s unclear how much of the code is written or review by humans. But they’re making changes to try to fix these vulnerabilities, and things are breaking. The Microsoft code is a giant fucking spaghetti mess, which means it’s bloated, slow, insecure, inefficient, and overall shitty. It’s not profitable enough to fix all of this, too. Fixing shit you already have doesn’t get shareholders attentions. So it’s AI in everything instead. New shiny stuff to keep the adult babies with all the money happy
