the firmware of my soldering iron just crashed

I haven’t used my soldering iron in over 20 years, but I know it is a simple electrical heating device with a thermal regulator circuit: firmware? Far more complex than valuable!
ah, a classic "I admit don't know what I'm talking about, but I'm going to say it anyway"

Then please, enlighten me: why would there be a need to have a soldering iron to have enough computational power to have reason to allow a change in firmware, assuming it can’t be done more simply in hardware alone?
-
sure. two main reasons. - if you're soldering something important, you want the temperature to stay within very tight bounds while varying the heat input by two orders of magnitude. this is normally done with a PID loop. oh, don't forget per-tip calibration too.
