Certainly possible

I'm also genuinely a little bit alarmed looking back now at my pre-LLM code and seeing the quality vs. the with-LLM code.

Yeah. I feel like in a few years when literally nothing works or is maintainable, people are going to have a resurgent realization of the importance of reliability in software design, that just throwing bodies and lines of code at the problem builds up a shaky structure that just isn't workable anymore once it grows beyond a certain size.

We used to know that, and somehow we forgot.

Yeah, exactly. If you read the Snowden leaks to learn the details of what some of their actual capabilities are (smuggling flawed keys into the DH exchange for most major web browsers for example), it makes this stuff look like kids in their basements fucking around.
