Our old pong console. I don’t know if it still works because it’s been boxed up for over a decade at this point.
Oldest in use? Probably my old texas instruments graphing calculator, but it’s dying. I got it back in the early nineties for college, and my kid was using it last year with homework, but the screen is failing and it sometimes just freezes until you pull and replace the batteries. So only kinds in use, and barely hanging on.
My VCR is newer and still sees use rarely, but was used daily for a few years in the early naughties.
Wait! The phonograph! It’s still functional and my dad got it in the early eighties, so it’s older than the pong console, but I think calling it electronics is dubious, so I dunno if it counts. But it’s the oldest functional electric powered thing we have that I know of.
I’m going to be blunt, this reads like reddit rage bait. As such, I’ll respond that way, then give a more neutral answer in case it’s real.
The response to it as bait is that anyone saying that seriously is an idiot.
More neutral, anyone saying that has an obligation to explain themselves because it makes no sense by itself. And it doesn’t.
