I'm GenX and since computers used to need more work, and my career followed the rise of computer software, I like messing with it. I am still often tech support for my millennial age kids, but the younger set (high school and college now) are outpacing me, especially the 19 year old. I maintain the home network but the 19 year old sails the seas for content, never needs my help with anything tech related, and can often help her older sisters with their questions now.

I would say the difference between us is that the younger ones seem to believe everything will work by itself, I believe most things can be fixed (and am delighted when it just works), the middle ones do not believe either of those things.
