As do I!
I imagine future archeologists finding them, however, with no method of power (or even a cord) and nothing to rotate the plate. Perhaps they will place razor blades inside: to see if they stay sharper, or fruit: to see if it stays more fresh.
It amazes me that the human mind has obtained the same moments of brilliance throughout its history and likely before it.
And thousands of years from now, the ritualistic removal of power cords from disposed microwaves will puzzle archaeologists.
