This is a short rant prompted by the fact that I'll have to wait longer than I expected for my dinner.
When I was a child, we had a simple gas oven. It had a mechanical thermostat that controlled the flow of gas. You set the thermostat, lit the oven, let it warm up, put the food in for the required time, and it was ready.
Now we have gas ovens with electronics. Temperature is controlled by turning the gas on and off, which requires that it be repeatedly reignited. Leaving aside the fact that this means that a gas oven doesn't work during power cuts, for some reason mine occasionally gets into a state where it refuses to relight the gas, and essentially turns itself off without any warning. The first one knows about it is when one goes to remove the food, and discovers that it's not cooked (though by how much is anyone's guess).
Ovens worked reliably 40 years ago. Why was it necessary to change the design to something that doesn't?
