I have a mother-in-law who has 30-year old electronic gadgets she has no idea what they are for... Image-search turns up no results... (A few are in their original packaging - those are identifiable - but typically useless)

Her box of random cables and "wall-wart" power supplies is huge - puts my old bin to shame... (well, I have since organized my "collection", labelled and sorted everything into many smaller storage bins - sighs... as the story goes, "oh - I no longer need this ancient connector/cable, so I will get rid of it", only to inevitably need it 2-months later, so now I keep them all, but label them...)

I resigned myself to re-buying things, though of course I love USB-C is a common charging cable.

Instead of a drawer full of wall warts, I have a drawer with a little baggie full of the ends of warts, which I connect via twisted wire if I have to to a few of the wall warts I have.

So true! I just recently found an old bag full of ancient phone and other device chargers and charging cables and let me tell you, it felt so weird. I have mostly forgotten that there used to be so many variations - every brand had their own version of what mostly is a simple power connector.

The best was physically identical connecters with vastly different voltage profiles, so if you plugged in the wrong one bam magic smoke is gone, sadness.

Yes, I am finally making the move to USB-C - and love it (even though I am the only person in the house that has a phone with it...)

Am extremely happy whenever a new device has it, and am making that a purchasing requirement from now on.
