Demis Hassabis: I’ve had quite a lot of “aha!” moments. I guess one of the really formative ones was when I first got my first computer. I was about eight years old. It was a ZX Spectrum. I remember starting to learn to program on it and sort of learning from books. I programmed some — one of my first programs I can remember was a program to play this game called Reversi or Othello. It’s called Othello in the UK, but it’s called Reversi, I think, in the U.S. And, you know, it played it reasonably well, and it could beat my kid brother. And I remember thinking, “This is amazing, that you can create a program that — you can go to sleep afterwards, and it can carry on number crunching — and then you can wake up the next day and it solved something for you that you wanted to know the answer to when you went to sleep.” So it seemed — again, I guess I was even then obsessed with efficiency — is that it seems incredible, like a way to enhance your mind, right? So, suddenly, you can outsource problems to this computer, and it can solve certain types of things for you. To me, that just seemed like magic and a magical extension of the mind. From then, I was sort of hooked on computers and programming and then, ultimately, AI.
