I like to set myself a new adventure challenge at least once or twice a year because I love that side of my life. I love getting fit and training for it.

We will be producing supersonic planes which will go far, far faster than Concordes. New York to Tokyo could be less than an hour. You could be traveling at 19,000 miles an hour orbitally.

Whether we're fighting climate change or going to space, everything is moved forward by computers, and we don't have enough people who can code. Teaching young people to code early on can help build skills and confidence and energize the classroom with learning-by-doing opportunities.
