At Microsoft there are lots of brilliant ideas but the image is that they all come from the top - I'm afraid that's not quite right.

I really do encourage other manufacturers to bring electric cars to market. It's a good thing, and they need to bring it to market and keep iterating and improving and make better and better electric cars, and that's what going to result in humanity achieving a sustainable transport future. I wish it was growing faster than it is.

Most of my ideas belonged to other people who never bothered to develop them.

Keep on the lookout for novel ideas that others have used successfully. Your idea has to be original only in its adaptation to the problem you're working on.

To turn really interesting ideas and fledgling technologies into a company that can continue to innovate for years, it requires a lot of disciplines.

A good idea is never lost. Even though its originator or possessor may die, it will someday be reborn in the mind of another.
