But there's just one invention that's supposed to change the world, though it's probably not going to.

In fact, there's a whole lot of inventions that were made and they were supposed to make big change and they just fell flat.

Luckily for us, there's an entire reddit thread.

The men's roof top 10, the men's roof top 10!

10. Inventions that were supposed to change the world, but didn't.

Dare I say, Facebook didn't change the world.

All it did was show us in a nanosecond just how self-absorbed, goable, and pathetically pathetic we are.

Oh, and tracking down that girl Tammy from sixth grade.

Not worth it.

Nice.

There's good and bad, everything, really.

So these are inventions that were supposed to change the world, but didn't.

One user says, smart cars.

Says they were supposed to be the next big thing that would save everyone tons of gas.

Everyone young and went back to their SUVs.

The only smart cars to see around seem to be rolling billboards for mom and pop businesses.

Oh, like the little, little T-ackel smart car.

I do miss car to go.

I realize service wise, there's no way to keep on the roads and terrible cars.

The smart car did not hold up.

No.

Well, the wrong car.
