Why does everything these days need a control board.

Not everything does.

In the past such mundane items simply cam on and off with a
thermostat.

But you can get a better result with more intelligence than that.

For example, with a car heater, you get a better result if the fan
only comes on when the engine is warm enough to be able to
heat the car.

which can be achieved by... a thermostat!

But not just the one that controls the heating
when the engine is a useful source of heat.

thank you for proving beyond the slightest doubt that you are a pointless
troll.

You never could bull**** your way out of a wet paper bag.
