When it became more and more obvious that computation is built into the laws of physics at a fundamental level, a lot of people immediately jumped to the conclusion, oh, well, the reason that mathematics is useful in physical sciences is that the world is a computer, and we are just programs running in that computer, or something like that, or we are just a simulation running in a computer. Now, it seems to me that that misses the whole point of the blessing of the universality of computation for physics, because it requires a notion of what is or isn't computable that is outside the physical world, so that it was set by God or something to be a certain set, and that's why our universe only instantiates that set of mathematical relationships. Well, then that doesn't solve the problem. You may as well have said that God set up just our universe with those relationships... Yes, removes the middleman. So I think the real, the important lesson of the universality of computation, as revealed by quantum computers to be part of physics, is that computers can be built, universal computers, can be built within the universe. That is really the amazing thing, because however the universe was, you could imagine some kind of super computer with unknown mathematics that simulated it, but the amazing thing about our universe is that you can make an object, such a computer that can simulate any physical process, that's what universality is, and this object, the set of all its possible motions, that is the set of all possible programs that could be programmed into it, is in one-one correspondence with the set of all possible motions of anything. And that is telling us something about the universe from the inside. It's telling us something about what laws of nature actually are. @DavidDeutschOxf

@_aphantasia This is life changing. I've been trying visual meditations ("active imagination") to engage with my subconscious & work towards Jungian "individuation," but now I "see" why this hasn't been working for me. Blackness. That's all I get. I never imagined it was different for others.

AI learns to write computer code in ‘stunning’ advance: DeepMind’s new AlphaCode outperforms many human programmers in tricky software challenges, representing a major step beyond the previous benchmark set by OpenAI's "Codex." science.org/content/articl… #nocode #lowcode #AI

Strangely enough, some cosmologists believe a previous, cold dark empty universe like the one which lies in our far future could have been the source of our very own Big Bang. bit.ly/3mUbtCA

RT @lsanger Larry Sanger, co-founder of Wikipedia, may be a thought leader in the same vein as Tim Berners-Lee. He was instrumental in creating powerful technology for the public good, & he's still fighting for the public good after his ideas were co-opted by corrupt interests.

Hey, @Wikipedia: propaganda is not knowledge! —They won't listen. But we don't need them. We're building an open network of all the encyclopedias. encyclosphere.org/the-encyclosph… But we need your help. Please give generously! #GivingTuesday | via startthis.org/?p=2390

nature has actually contacted me for comment about accusations that Sci-Hub is a threat, here is my full response / it is clear that academic publishers care about their money, not about security of other people
