Oh right. Along those lines sometimes I do long hand multiplication or division instead of using a calculator. I think it's a valuable skill. If I don't do it, I'll probably forget how.

Yep! But if I were doing my job as an accountant, I would not spend time doing any of that work using long hand division, I would use a spreadsheet. To me, it's a professionalism thing. If I'm doing a job, I should use the best tool (for me) for that job. (edit: I'm absolutely not suggesting that you are unprofessional! It sounds like AI tools are not the best tool for the job, for you. But they are for me, at the moment.) If I'm doing a hobby or personal development in general, then I can use whatever tools I want for that.

It's interesting though, for a long time I said that if I were going to do a personal programming project I was excited about, I would write all the code by hand, because I do really miss doing that, and I also worry about forgetting how to. But now I'm not so sure. I find my daydreaming about personal projects to be a lot more focused on the outcome than the process, lately. More like "wow, I could do so much in an hour or two a day now! think of the possibilities!" than an excitement about writing code and creating pleasant abstractions.
