I think that the semi inherent nature of technology means that they complicate the process. It is adding moving parts to a system with no need of them therefore it makes the system needlessly complex and require management via apps

The smart part would be a temperature sensor, a connection to the spark, and a potentiometer or something to control the temp. The regular old button for the spark would be connected in parallel so it still works if the computer is down. Similar for the knob. Absolutely no interference with regular operation, so the extra complexity doesn't matter.

if someday it becomes feasible to connect a spoon to the internet of things it would still be a silly idea as a computer chip is like any mechanical component only useful for the thing it does well and sometimes that doesn’t make sense to add.

But the spoon would still work if the chip died. That's my point.

A lot of smart technology feels like they decided to add it to the internet of things and then tried to find problems for that to solve. Which is putting the cart before the horse

It is, but who cares. If you don't think it's useful to you don't get it.
