Also it helps when you have people around you using them, showing you new stuff, giving an idea of what is possible, etc. I learned lots about computers just from seeing what other people could do with them, getting ideas about what might be possible and knowing what to look up to find out how, etc. My Mum has much less idea what sort of things phones/computers/internet are capable to doing, so it doesn't occur to her to look it up and find out how
I now work on my own, no children, etc so don't get exposed regularly to new technology in the same way, and it is harder. There are way too many choices, and the effort sometimes to work out what I want is harder. I don't know how to get music on my iPhone as easily any more, for example. There's apple music, there's spotify, there's amazon music, there are a few things I used to have in iTunes that used to come from physical CDs, etc; some need subscriptions, some need internet, some have ads, some let me keep the music longer term, some go on all my devices, and I just can't be bothered to figure it out so I don't really have music on my phone now. If you don't see other people using things, if you don't start to get an idea when they first come out, and you then later on try to understand it, it can seem a bit overwhelming, too much choice, too much complexity, and you sometimes just have less energy to care about it. And I'm only in my 50s, so I'm sure I could do it if I had to.
