Maybe. Take fuel injection as an example. You used to need to adjust carburetors for altitude, environment, performance; today, an engine's computer auto adapts. It can be modified but the specialization required is much higher with much less reward. Take computers as an example; 30 years ago, and updating an OS took hours and a dozen floppy disks, installing a new program took purchasing it, installing via floppies, now we have app stores and wifi. (Installing apks not from store is an example to still get this technical detail and satisfaction). Take networking; a single access point is solved, but if you explore into mesh, or figure, hey, i stream 4k there a lot, i should use cat5, it's exciting when you solve the problem.
