This cockroach-like existence is cumulatively intolerable even though on any given night it is perfectly manageable. “Cockroach” is of course an allusion to Kafka’s Metamorphosis, in which the protagonist wakes up one morning to discover that he has been transformed into an insect. The point of the story is as much the responses and incomprehension of his family as it is the account of his own sensations, and it is hard to resist the thought that even the best-meaning and most generously thoughtful friend or relative cannot hope to understand the sense of isolation and imprisonment that this disease imposes upon its victims.

Very often I had to fight for the recognition of my ideas, particularly since, in those earlier days, I wasn’t in any prominent position where people would listen to me.

In terms of this issue of these industrial gases affecting the environment, at the beginning the road was not easy, because we were suggesting that society had to change, that industries had to do something different than they were doing at that time. And of course, initially we did not meet with a good reception to these ideas from industry. And even from the scientific community — even though our ideas were well received in the small group of specialists in what we were doing — it was not necessarily well received by the scientific community at large. So we really had to continue doing as good a science as we could, and at the same time trying to well communicate our conviction that it was something important, something that had to change in the way society was functioning.

I would say there are many challenges, and that's kind of what's hard about it. And my particular thesis, since leaving Google and doing my own company, is that building a quantum computer is a little bit harder than the scientists think about because of the system engineering. Building a powerful computer is hard. So what we're particularly working on is the manufacturing of qubits and doing that much better than what people are doing right now. I really enjoyed being in academia, and even at Google working on that. But I really enjoy right now trying to think very practically about what we have to do to get this to work. And what kind of people we have to collaborate with in order to put all the pieces together and build a quantum computer in a cost effective, economic way that makes business sense.

Preferably not as the guy who played Gollum.

It’s hard because I’m attached to so many of my roles for so many different reasons,” he says. “But I do have a special affinity with the role of Gollum because, not only was it an amazing character to play, but it spawned a huge change in direction of where I was going as an actor: working in the digital realm.

During the ’80s, when I was in college, on the American side, it was Robert DeNiro in Taxi Driver, Robert Duvall and Martin Sheen in Apocalypse Now, Christopher Walken, John Savage, John Cazale, etc. All of those guys – I was blown away by the emotional impact and sincerity of their performances. And then of course, in the UK, I was going to a lot of theater at the time and watching great on stage performances from people like Jonathan Price, Albert Finney, Anthony Hopkins – all of whom really influenced me as well.

Strength, comfort, joy and passion.

When my wife Lorraine and I got together in 1990. We were in a play at the Royal Exchange theatre in Manchester when we suddenly realised we were falling in love.

I am a workaholic. I love what I do, but I am aware that it can become obsessive.
