Windows 10 would be a completely different operating system had Bill Gates's predictions been true:
We want to show you a collection of other similarly-stupid predictions that have been made by some of the world’s leading innovators. Why? Well, basically just to prove that we can all make mistakes from time to time, and that we can only move forward if we question our beliefs.

Let’s see what other geniuses have come out with over time!

So, there you have it! Everyone makes mistakes - even some of the biggest geniuses the world has ever seen. What does this say about us? Well, that we certianly shouldn't cling on to our beliefs... and should question everything. Clearly, nothing is impossible!
