I don't recall if the list has discussed these ideas of David Deutsch recently. The link is to an Edge interview in which he discusses his view that mathematicians are mistaken if they believe that information or computation are purely abstract objects. He says that both are in fact physical, but to justify that assertion we may need deeper principles of physics than the existing ones. He proposes constructor theory as a candidate. Implications for comp (or anything else for that matter)? David -- You received this message because you are subscribed to the Google Groups "Everything List" group.
