No more toll booths

It's funny how computers are taking over totally slowly but surely. No more toll booths, cashiers, janitors in some places and there is even a computer or machine that builds houses, "3D printing". Check it so this means no more construction workers soon.

 There are computers that anyone can buy now that, to put it short, prints/clones things it's programmed to clone or make. Amazing. 

My mother said we are getting to the end of time lol! I told her time never ends its people who's time expires.

Will it ever get to the point where there are more sellers than buyers and will major corporations survive when there are no more consumers?
