A hole in your tooth? In the future we should be able to fix it, are we? NO! We drill the hole bigger and fill it with weird stuff.

Vacuums. Your dog is afraid of a noisy vacuum? Why are they still noisy after so many years? There are better ones but they are very expensive and not in a normal store.

Restaurant menu. You want to go to a fancy restaurant, book a table, wait a week or so and... spend some time reading the menu, sometimes in French. People say if pizza places post menu online why can't you pick your meal beforehand?

Fax machines? We still use those? Why?
