I’m an old school coder. I haven’t vibed. I’m guessing the “who is going to maintain this” could only be another tool similar to what built it. I can’t imagine trying to get my head around that much code in a timeframe acceptable to someone demanding product. So are we headed to a place where everything is written and maintained this way or a lucrative future of having to get these things to work properly.

Given amount of duplication and variation there is no way to guarantee any level of security in such codebase. The bright future ahead!
