I went through a similar process when I switched to Teslas. I had fond memories of working on cars with my Dad and when I did the things he taught me I felt connected to him. Of course there were plenty of frustrating times when we'd strip a bolt, bang a knuckle, having oily bots of dirt fall into your eyes while you're taking something off, etc. I certainly don't miss those parts, but we always made it through and we'd sit back with a beer and laugh about how we'd done something stupid and had to fix it.
I also felt that I would miss passing those skills on to my kids.
But over the last few years I've realized that I have more time to just go out and do other stuff with my kids, instead of working on cars with them. It also seems that dirt bikes need love beyond the drive train (I've never adjusted a spoke in my life) so there are still jobs that need to be done. Finally, you can obsess over charging regimens, the perfect place to run outlets in your garage, etc.
