Suit yourself. A high power vacuum tube then.

Also, they don't "generate" power.

OK -- The high power vacuum tube at the heart of a microwave gradually
uses itself up and unit puts out less and less power as it grows
older. Also, modern microwaves output more power to begin with than
older units did when they were new.

Happy now?

No. You're blowing the degradation out of proportion. They might drop
5% by the time the power supply craps out. BFD.
