I'm not sure I can think of anything that's less efficient now compared with 60s-80s tech? EV vs ICE, LED vs Incandescent and so on.

What kind of things were you thinking of?



Repairable vs unrepairable, local production able vs needing huge global coordination and resources, "dumb" devices (ie better) vs "smart" and IoT, less tech vs more tech encompassing more areas, more public transport and trains and less cars (including electric cars), and other such things...
