For me, the idea of a wearable computer just seems like a waste. And I think much of that comes from the fact that I've done most of work analytical work with pencil/pen and paper. So for me technology is the thing I use to do work I could never do on a notepad or in my own head. It took me years to finally accept the idea of a password manager so I would stop reusing the same set of passwords all over the web whenever I created an account. Heck, I didn't even have a smart phone until 2014 since I still prefer the flip phone form factor. And I'm only 37 so I do think technically minded people tend to like using their own mind to do the work much like an athlete or a farm worker likes to use their own body to do physically taxing work. It's just a natural fit in that regard. For everyone else, convenience trumps practicality.
