My mother had a dishwasher in the late 70's that didn't work properly. I think it was very expensive at the time.

She used it's crumminess as justification both to wash all of the dishes manually, and to never buy another dishwasher again, since she would obviously have to wash all of the dishes by hand anyhow. The thought that technology might improve over time never seemed to occur to her.

I get the idea that she was not alone in that.
