I don't know, I think things like refrigeration or electricity or antibiotics were pretty visible. The closest I can think of in more recent times is the invention of the blue LED, which, it was obvious would open floodgates to 10x more efficient lighting. Maybe power semiconductors too, which unlock inverters for EV or solar. But it still doesn't compare in quality or quantity to early 20th century IMO.

Not wrong, and I wouldn't want to 'regress', but compared that to going from using gas lighting and candles to the incandescent light, the introduction of LED lighting isn't as much of a step change. Also remember that there was a noticeable improvement in efficiency with fluorescent lamps pre-1970s: * https://en.wikipedia.org/wiki/Fluorescent_lamp https://en.wikipedia.org/wiki/Fluorescent_lamp

  Oh absolutely. The fact that that’s the best I could come up with is what concerns me the most.
