You must live in a museum. :-)

Maybe your oven has a touchscreen and apps on it but it basically still heats your food by converting electricity to heat.

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.

And people do seem to love to contradict and argue.
