Invention is not enough. Tesla invented the electric power we use, but he struggled to get it out to people. You have to combine both things: invention and innovation focus, plus the company that can commercialize things and get them to people.

If you can run the company a bit more collaboratively, you get a better result, because you have more bandwidth and checking and balancing going on.

You don't need to have a 100-person company to develop that idea.

For me, privacy and security are really important. We think about it in terms of both: You can't have privacy without security.
