I guess they are assuming LLMs will just get better and better until youn don't look at code at all.
Ignoring the fact that software will just keep getting more and more complex and interconnected... There will always be a new frontier or code and UX
They're targeting the 90% of code that doesn't really need to be looked at. Software is already so complex and interconnected that it is fully beyond human capabilities, each person only knows a tiny part of the stack. If you create your own full system from scratch, it's not going to be very generally useful.
