I've met people in their 60s who distro-hopped over a dozen+ linux distributions just to see what they're like, as I did in my teens, and also priced out a 3d printer from numerous options until settling on one that they bought and used to tinker and make many useful things for their home (something I only wish I could have done in my teens but 3d printers weren't available then.)
But they like you, are the minority, not the majority. Most people slow down and at some point stop learning new things and cruise on what they know until they die or hit a wall of obsolescence and then die.
'Many people die at 25 and aren't buried until 75' is a very real, very sad thing.
Kudos to you for continuing to learn new things, it's truly inspirational.
Those are the things you can't even learn effectively until you get quite a bit older.
