Inbound anecdote.

Dad worked for Corning; when they hired him, he bought a house one town over. It came with a Corning electric range in the kitchen. This was effectively four electrical resistance grids embedded in a giant sheet of pyroceram.

Like an induction cooktop, there is no visible indication that the "burners" are "lit", unless you looked at the control panel off to the side.

Somewhat like an induction cooktop, only certain cookware was compatible with it. Luckily, the primary requirement was "the bottom needs to be flat". You might be surprised at the number of pots which have concave bottoms... or develop them over time.

UNlike an induction cooktop, it does get up to arbitrarily high blackbody temperatures.

Pretty much every accident you can think of synthesizing from these conditions occurred. Nobody in my family would ever buy one. (I love lots of other Corning products.)

Oh, and as for the easy-to-clean surface? Very true... as long as you ignore the case of scorched proteins. Anything else, you wait for everything to cool and then wipe it with a slightly soapy sponge, then mop with a damp cloth. I don't remember the night the grey scorchmark appeared, but it lasted about fifteen years. Then Dad sold the house.

Cookware that isn't flat is usually because it is warped, which happens if you mistreat your cookware with thermal shock.
