The research community rallied behind the Turing Test as a benchmark. The idea was simple: demonstrate that machines can emulate human intelligence, which was seen as the pinnacle of cognitive achievement. This historical and cultural trajectory, while understandable, seemingly dismisses the idea that computers can serve as invaluable complements to human cognition.

If people really want to do something, all they need to do is meet someone who's built something from scratch to show them that it can be done by someone just like them. That's how I started.

Endurance is mind over body. It's about tapping into something within us that allows us to push further than we ever thought possible, especially at our weakest moments.

We're outnumbered by bacteria 1.3:1, we're slightly more bacteria than we are human. We're also stardust. We are also 60% water, and that water in our bodies is billions of years old; it's been the clouds, the bottom of the sea, waves, streams and everything in the cycle. At an atomic level, 98% of the hydrogen in our bodies came from the bigbang. We're incredibly ancient beings, perhaps we should see ourselves as aliens!

The crux of the matter is the internal liberation that comes from acknowledging that there will always be more to do than we can handle, and that certainty about the future is unattainable. It's a form of defeat, yet immensely productive, because as long as you believe mastering everything is just extremely challenging, you'll continue to struggle.

Contributing to society comes in many forms. Meaningful careers not only fulfil our team members but also drive the broader economy as employees become taxpayers. This virtuous circle is a fundamental contribution to society.

My advice is to grab hold of people that are close to you and lean on them heavily. That's how we're designed to work!

There's also of course this huge army of paid trolls (like Putin's) who can be hard to spot, but definitely there, whipping up hate and confusion just because it's part of the Russian state process to do that.

The people in the advanced countries now face a choice: we can express justified horror, or we can seek to understand what may have led to the crimes. If we refuse to do the latter, we will be contributing to the likelihood that much worse lies ahead.

It takes intellectuals to come up with some of the most moronic ideas possible.

On the night of my 30th birthday, I was at a bar in San Francisco... I walked out of that bar at midnight, drunk. I didn't even own running gear, I had some comfortable silk boxer shorts on – took off my pants – and took off down an alleyway stumbling south without knowing that a town called Half Moon Bay was nearly 30 miles away. When the alcohol wore off, I had this epiphany. I looked up and saw heaven – I saw the stars – it was the first moment of clarity I had since I'd given up running. It made me realise that perhaps I was on this earth to be a runner – I wasn't happy being a business guy, it was making me miserable. I was comfortable, but miserable.

The learnings I had as an athlete about communication and motivation- and even how we worked with companies and brands- really have helped me in this new journey but most important has been the realisation that I have to stay true to myself, and find that same passion and focus in entrepreneurship as I did in athletics.
