What have been the most important and/or surprising physics results in your career?
I had one big negative surprise, as did much of the community. This was a while ago when the idea of “technicolour” – a dynamical way to break electroweak symmetry via new gauge interactions – turned out to be wrong. Everybody I knew was absolutely convinced that technicolour was right, and it wasn’t. I was surprised and shocked. As for positive surprises, I think it’s the whole collection of ideas called “it from qubit”. This has shown us that quantum mechanics and gravity are much more closely entangled with each other than we ever thought, and that the apparent difficulty in unifying them was because they were already unified; so to separate and then try to put them back together using the quantisation technique was wrong. Quantum mechanics and gravity are so closely related that in some sense they’re almost the same thing. I think that’s the message from the past 20 – and in particular the past 10 – years of it–from-qubit physics, which has largely been dominated by people like Maldacena and a whole group of younger physicists. This intimate connection between entanglement and spatial structure – the whole holographic and “ER equals EPR” ideas – is very bold. It has given people the ability to understand Hawking radiation, among other things, which I find extremely exciting. But as I said, and this is not always stated, in order to have real confidence in the results, it all ultimately rests on the assumption of theories that have exact supersymmetry.

True progress lies in the direction of decentralization, both territorial and functional, in the development of the spirit of local and personal initiative, and of free federation from the simple to the compound, in lieu of the present hierarchy from the centre to the periphery.

On a windy, rainy, spring day, I am happy I have no visitors; my hand is free, my mind relaxed and cleansed. The ancients called it yihua, the "single stroke": a thousand hills, ten thousand valleys, people, bamboo, trees,a single brushstroke and all is completed.

I think Kyoto would be much more fun actually

How about Kyoto ? I live there so might be able to answer general questions
Its been awhile since I read this but it seems to me you kinda got to treat it like quantum field theory. It has tremendous descriptive / predictive value so something is clearly correct but the math is impossible. Graeber's book is a bit like that and its the framework in which it is elaborated which is very hard to pin down. Is it Venetian 12th C treatment of debt or Aztec treatment of debt ? In his narrative they can occur simultaneously. So best I think to treat it gently and with respect and see what can be learned from a somewhat loopy [ at times ] narrative. A bit like art I guess.
