If you have find a beautiful algorithm, and your boss asks you if you have implemented it, well, if you have not implemente, there is a sense to say the algorithm is un-implemented relatively to you and to your boss. Of course you can tell your boss that the algorithm is implemented an infinity of times in Plato Heaven (or in the standard model of arithmetic), but he will probably not be satisfied with that answer. > > > But all possible implementations is a logical concept that exists only > in platonia - so what is the distinction between implemented and > un-implemented computations. I was discussing with Kory, where we were meaning "un-implemented" by "not implemented in the material world", assuming there is one, or for those who grasp UDA (including MGA): un-implemented means un- implemented relatively to the most probable computations executed (mathematically) by the UDA (interpreted in any model of arithmetic: the "running" is itself a mathematical object). Brent, have you understand the seven first step of UDA? Then you shorld understand that the only correct way to predict, in principle, any experiment (like dropping a pen) consists in putting a measure on uncertainty on the set of all computations going through your state of mind when you are doing the experiment, and seeing what happens in the "majority" of computational histories. All right? Don't worry if you don't like that, you will still have plenty of reason to criticize the proof by objecting on MGA. the UDA-without MGA is the easy part. MGA is far more subtle and complex. The complexity stems from philosophy of mind.
