“I’m a sucker for stainless steel. It maintains its integrity forever – or for about 1000 to 2000 years. The rust you get from stainless steel – chromium dioxide – is both adherent and non-permeable. So it stops and stays stopped. So, in the various factories that we went through, because in many cases we’re dealing with human contact-grade stuff, and everything has to be wiped down, it’s stainless steel all the way through. In every factory, I go, ’Ooh, I love this stainless steel!“.

Those three things have put us in the weird place where we are right now … If we understand that the world is not a mystery, but understandable, we can then work out what things truly are mysteries. Trying to get people introduced to all these wonderful things that humans can do is part of the whole process of trying to bring light into the world.”
