Business idea that I’m working on:

Home appliances that are as analog as possible while being efficient.

My washing machine doesn’t need wi-fi.

My stove doesn’t require a subscription.

My fridge doesn’t need to have a screen shoving ads in my face.

And all of them should be trivially repairable.

I know there are enough people who have guns pointed at their printers in case the printer develops an attitude; I’m certain there are people who would go for this.
