We have a lot of phobias around algorithms. Sometimes this is justified, but in the main, it's like being afraid of cockroaches or spiders. Algorithms aren't spiders or cockroaches, they're an instrument and sometimes will outperform human judgement terrifically well – and sometimes won't. If lives are on the line and it turns out an algorithm reduces the noise of the human decision maker and the bias, then the moral case for using the algorithm starts to look really strong.

I started to get concerned about the natural world as a child and there are 2 images that I remember always from my childhood. In London Zoo, I remember the sound of the iron doors that clanged behind us as we went in. And there they were… these wretched creatures, walking up and down their very small caged area. I hated it! I absolutely hated it without knowing why really, at that age. Later in the Kruger, I saw a group of lions, obviously a pride, sitting peacefully and calmly under a tree. And these two contrasting images in a way became symbols for the rest of my life and the way I think about wildlife. One is how not to keep them, and one is how to leave them alone where they should be.

If one wants to treat societal problems, then philanthropy and government spending are fine. If one wants to cure societal problems, one has got to come up with sustainable solutions- and that means attracting for-profit capital.

The most powerful stories come from genuine human connection. When you truly understand someone's experience, you can translate that into something universal that resonates with audiences everywhere.

My early experience as an unaccompanied child refugee on the Kindertransport brought me to England in 1939, evading Nazi Europe. That really had an enormous impact on me, everything was different. It was such a big change, that change doesn't throw me anymore. I've learned to enjoy change, I like to do new things, make new things happen. I'm also very conscious that my life was saved, and I decided, very early on, to make mine a life worth saving.
