A lot of things haven't changed at all. Televisions (apart from the screen itself), most kitchen and household appliances, all almost exactly as they were 50 years ago.
Maybe your oven has a touchscreen and apps on it but it basically still heats your food by converting electricity to heat.
And people do seem to love to contradict and argue.
Nope, mine uses electricity to radiate microwaves.
Which are by dielectric heating converted to heat...
Well, sure, if you want to heat something, you must create heat. That's a tautology. But it's not true that the appliance is almost exactly as it was, it just has the same goal.
