> Why does an oven need a computer in the first place? What do you mean? What else is going to control the temperature, display, timer, etc.? I’m pretty sure my oven from 25 years ago had what I would call a “computer”.

My oven has a knob that I manually twist. To timer. No display at all. Not much electronic at all.

  That’s how my old gas oven was, and now I miss it!

You could do it all with discrete chips on a board. No need for a computer really. Temperature -> PID controller, display -> 7 segment decoder, timer -> timer chip. Something like a circuit board with a bunch of discretes would be how I would expect an oven from 25 years ago to look. Maybe there's a microcontroller to coordinate things, but I think you could get by without it

    Why do you want them, exactly? If I want to set a timer, I can just speak and be heard by one of the phones, tablet, watches, and orbs dotted around the place which collectively cover all three main voice assistants. And what's to display? It's an oven, not a website. Temperature is a dial, is it hot enough or not is just yes/no.

      You really can't fathom why someone would want a timer on their oven? The things HN posters will be willfully obtuse about is incredible.

        I get why "a timer" is useful. It's specifically "on your oven" which is the part that makes no sense. We get as many timers as we want, whenever we want, summoned out of the αἰθήρ as needed whenever we invoke the names of the synthetic húsvættir that have shipped in all our phones for the last decade or so. The question is "why do you need yet another one?", and the fact you think it is so important that it has to be specifically embodied on an oven as to be flabbergasted that I don't think it's important, seems… well, I won't call you "willfully obtuse" because I recognise how minds other than mine work differently, but it does seem very silly.

      It’s simple: convenience. Just like your Internet connected listening devices.

All you really need to control is the temperature. You don’t need any electronics at all to do that. You can just use physics. https://www.cookerspareparts.com/news/post/gas-oven-thermostats-what-you-need-to-know https://www.cookerspareparts.com/news/post/gas-oven-thermost...
