"The structure of all computations". Lets go physicalist even on this one. Where does such a mechanism exist? Is it dark matter? the area beyond the Hubble Volume, the unborn minds of humans and AI yet to come? Phase space Hilbert Space, Anti-De Sitter space??? A future Omega Point, a

IRREVERSIBILITY is an artifact of the CI, where collapse occurs to an eigenstate of the observable being measured. But if the measuring apparatus is treated quantum mechanically, all processes associated with measurements are unitary and reversible. On Saturday, August 13, 2022 at 12:47:06 AM

That's defining IRREVERSIBLE FAPP. OTOH, if X and Y produce Z at any time, I don't see any way to reverse the process, so it's IRREVERSIBLE IN PRINCIPLE. Do you agree? AG On Saturday, August 6, 2022 at 5:02:17 AM UTC-6 johnk...@gmail.com wrote: > On Fri, Aug 5, 2022 at 6:47 PM Jesse Mazer
