Everyone's wrong about what AI does for experienced developers. I know because I've just used it on a 21 year old code base. I run a website that was launched in 1997. It's one of Canada's longest running web services. It started in PHP, but I rewrote it in Ruby on Rails in 2005. Last week, I opened it up with Claude Code. First real attention it's had in years to be honest, and here's what I found. Every AI conversation in the developer world right now is about fear. Your experience is worthless, the machines are coming. The headlines all point kind of in the same direction, but sitting inside a code base I know deeply with a tool that can read it all instantly, that experience wasn't a threat. It was leverage. The AI can see every line of code. What it can't see is 21 years of why. Why the data model is shaped the way it is, how certain tables are accessed in ways that aren't obvious from the code alone, which parts you touch carefully and which you shouldn't touch at all. It kept running into things only I could answer. That's not a limitation of the tool, that's kind of the point. If you've built something real, AI extends you. If you haven't, it exposes you. That's the version nobody's telling, probably because it's less comfortable than the one about robots taking your job.
