No, I do mean it literally. The wheel is a pretty basic invention, and yet tire manufacturing is a $140 billion industry that spends a great deal on research and development.

When you think a problem is solved, it's actually in a perfect position to be disrupted.

Are you familiar with the phrase "reinventing the wheel"?

[nkohari]

Yes. My point was that there's a huge amount of effort currently being expended to do just that. No one is trying to change the fact that a wheel is round and rolls, but from there, there's quite a bit of space to innovate.
