Interesting. I still have no problem with it, of course, buttressed by my quick glance at that page to see, at the very top: Warning: The central idea in today's post is taken seriously by serious physicists; but it is not experimentally proven and is not taught as standard physics. Today's post draws heavily on the work of the physicist Julian Barbour, and contains diagrams stolen and/or modified from his book "The End of Time". However, some of the arguments here are of my own devising, and Barbour might(?) not agree with them.

Yeah. Despite the disclaimer, he then goes on to assume it's literally true. And, for relevance to this post, he does so in the story as well, in Chapter 28. su3su2u1 (who is an actual physicist) discusses the problem in http://su3su2u1.tumblr.com/post/98526012853/chapter-28-hacking-science-map-territory http://su3su2u1.tumblr.com/post/98526012853/chapter-28-hacki... : > There is no “true math of quantum mechanics.” [...] These are different mathematical formulations, over different spaces, that are completely equivalent. > What Hariezer is doing here isn’t separating the map and the territory, its reifying one particular map (configuration space)! >I also find it amusing, in a physics elitist sort of way (sorry for the condescension) that Yudkowsky picks non-relativistic quantum mechanics as the final, ultimate reality.
