That's fine for simple work, but soldering can absolutely benefit from a temperature controller. That's either a simple analog controller, or a microcontroller that has a display, menu, and consecutively, firmware. There is nothing complicated or "eccentric" about that in case of a soldering iron.
I'd even argue it's the same with the device in the original post. I get it's a joke, but let's face it, that's not simply a kitchen knife.
Now if anyone can tell me why the fume hood in my kitchen is wifi - enabled... I never hooked that up, obviously, and all I can think of would be push notifications in case of an upcoming filter change, you know, the thing that could be implemented with a simple LED for 4ct.
