I agree that it's an opportunity to "do it the old way", as a way to preserve the skill. I actually would like to do that regularly, like half a day every week or something.

But I find it difficult to motivate it from the "productivity" angle. Like if I work for a day without an LLM today, it feels like I could go skiing instead, and the LLM will do what I would have done today in 10min tomorrow...
