Kind of both. Simple things like the switches on ffmpeg to rotate a video, is one example. I do that infrequently and Claude got it right in one. Quicker than reading the ffmpeg man page for that information by a long way. Also basic utility scripting something like "give me a golang program that connects to a Docker instance and returns information in this format". I could write it but a lot slower than an LLM

As to the age thing, well I doubt it. I started on the Internet in 1995, and I've been on it ever since. Sure I can skim by fake results but it slows it down as the good results are ever fewer on the page. I can do it but LLMs are faster and avoid all of that.

Also by using them more, I get a better sense for what will work and what won't work, improving my velocity again. It's easy to spot that they're good for things that are widely done, so more common and widely used commands and languages.

They fail hard on novel or new things, for example OTel code is one place where they're bad, and also deeper parts of things like k8s.
