Progress + Efficiency are an Illusion

My microwave from 1990 doesn't shut off any more. But for years we used it with a kitchen timer. Recently our pal Steve gave us a microwave he salvaged from a kitchen job. This one does shut off but the beep sounds like a smoke alarm and scares our dog to death. So now when we want to heat up our coffee we have to take our dog into the backyard and run back inside and set up the coffee and then run outside and wait. Progress and efficiency are an illusion.
