they don’t glow from heat but they can glow by design: for safety reasons, some have lights that simulate glowing from heat. I guess the choice of image is a little curious, given the primary distinction between induction vs. traditional is, typically, the absence of external heat.

At risk of sounding dangerously stupid, what exactly is the safety concern? Given that induction is cool to the touch, it's not obvious to me how you'd hurt yourself (which is doubtless another major advantage of gas).

They're not cold to the touch once they've been used: the induction process heats the pan, but heat from the pan will transfer back to the glass. If you use an induction cooker for 20 minutes, and then immediately place your hand on the glass, your hand will be burned.

Which is great for safety. Yes it gets hot if a pot has been boiling for a while, but it's a far cry from regular resistive ceramic tops.

Just bringing some water to the boil is not enough to make it more than uncomfortably hot. Try touching a resistive heater top after doing that...

The article mentioned that some induction ovens come with lights attached to emulate the feeling of fire…

My (Samsung) induction-capable cooktop has resistive heating as a "backup" for cookware that is not induction-compatible. Theoretically this can be disabled using an app, although the app has never worked.
