I do miss the heyday of LEGO Mindstorms. Everything seems to have moved to low-cost limited use sets you can get on Amazon. Lowering the bar of access is a good thing, but I do miss the feeling of having a big tub of LEGOs you could build anything you want from.

I guess the cool kids learn CAD and just 3D print the parts they want, which is also awesome (I wonder if there is any research in recycling failed designs or prints back into filament)

I certainly do that with PCBs these days. The cost went down so far I just throw a design together in kicad and have them made for me and shipped over in a week or two. It's only a few bucks more than ordering protoboards and doing all of the wiring myself. I'll exchange a lunch out for that convenience.
