Newish buzzphrase: IOT = Internet of Things. What do I need to know about it?

I have several very old, definitely pre-IOT potholders here, that are starting to fall apart with age. It’s clearly time for me to get new potholders, as the ones I have are no way upgradeable. Should I be looking into IOT-enabled potholders? Why or why not? What advantages would they have for me?

(Note: I do very little cooking.)
