>Usually I spend the time up to T-3s wondering how the crazy beepers on microwave ovens is still a thing, generations after the novelty has worn of.
Because, for at least 40 years, it has always been something you can turn off. It's like two sentences in the manual. They often have more options than off/on too.
It's astonishing to me how often people own something, don't read the manual, and then complain about something that already exists.
I read every instruction manual I ever had access to. There used to be tons of great info in them, niche use cases explained clearly, things to watch out for, how to know if it needs maintenance etc.
But nobody every read it, so now manuals have nothing, and the people who used to be paid to write all that important info are gone, and all the features they helped sell and the quality they helped emphasize is gone. I'm so sad.
The problem with turning it off is they usually don't keep the settings when you have a power outage, and often not even a power flicker. So then you need to remember to set it every time it loses power... pretty soon you just give in and open the door as the time expires.
