To be fair most code in most shops I worked for since 2011 was crap with some notable exceptions. People came and went, teams forgot why code was written or what it did, or randomly rewrote stuff that just worked to replace it with crap that didn't, over-enthusiastic rookies wrote over-complicated code to impress their seniors, early code debt was calcified into impossible monstrosities that couldn't be refactored without bringing entire systems down, etc.

But I'm sure in a few years AI will be so good we won't have to worry about any of that anymore. After all, it's not like those systems learn how to code by reading our code, is it?
