My analogy holds up. Anyone could type "optimize my PostgreSQL database by editing the configuration file" into an LLM, but most people won't - same as most people won't watch YouTube to figure out how to unblock a sink.
If you don't like the sink analogy what analogy would you use instead for this? I'm confident there's a "people could learn X from YouTube but chose to pay someone else instead" that's more effective than the sink one.
You're exactly right (original commenter here). I began my career in professional software engineering in 1998. I've despaired that trained monkeys could probably wreck this part of the economy for over 25 years. But we're still here. :D
