I think the drop in tinkering is due to the high skill/cost barrier to entry particularly SMT, and lab equipment. If you want to do anything interesting beyond a breadboard and arduino/rpi you are going to need to invest in a custom pcb and lab equipment. With SMT, I got into EE/HW by taking things apart and studying them, back then (late 90's) most consumer stuff still had a good mix of thru-hole and SMT so tinkering was easy. Now almost nothing is thru-hole so if you want to fix or modify anything you are going to need more than a cheap harbor freight soldering iron.

Custom PCBs have been $5/square inch for a set of 3 from OSHPark for many years.
You can buy a usable hot air station on Amazon for the price of a DoorDash meal.

repair is definitely not the gateway it used to be, though
