From: "Stathis Papaioannou" <[EMAIL PROTECTED]> But the problem with ontological type arguments is that they allow you to conjure up anything you like by simply defining it as existing. If there is a physical reality, things don't work like that. Statements of mathematics and logic, however,

From: "Shane Legg" <[EMAIL PROTECTED]> For sure. Indeed my recent paper on whether there exists an elegant theory of prediction tries to address that very problem. In short the paper says that if you want to convert something like Solomonoff induction or AIXI into a nice computable system

From: "deering" <[EMAIL PROTECTED]> It should be a fairly obvious implementation of a nested quantum computer to run any of these infinite processing programs. We will soon have oracle type computers that can answer any question with the reservation that the top level of the nest will have

From: "Stathis Papaioannou" <[EMAIL PROTECTED]> and which is not so muddled as the crypto-idealist suggestions that any 'mathematical structure' or any 'program' defines a possible world. Why that last phrase? There is a great elegance and simplicity in the idea that all mathematical str

From: "John Ku" <[EMAIL PROTECTED]> I actually think there is reason to think we are not living in a computer simulation. From what I've read, inflationary cosmology seems to be very well supported. [...] Once you admit that you (and your whole species/civilization, assuming that it was real)

This is a good idea but some of the numbers seem wrong. In the first scenario, the simulator is the computer connected to my brain (or the software running on that computer, if you prefer); why should a synapse count provide a good estimate of its complexity? And the complexity of scenario fi

Richard Loosemore: In fact, if it knew all about its own design (and it would, eventually), it would check to see just how possible it might be for it to accidentally convince itself to disobey its prime directive, But it doesn't have a prime directive, does it? It has large numbers of const

Or to put it another way: there is no rational basis for the belief that Something Big will happen in 2012, specifically. It is an apocalyptic date from an ancient calendar (let's call that an ADFAAC) that happens to coincide with the epoch of the silicon revolution on this planet. Well, as I
