But talking about the difference between Von Neumann architecture and non Von Neumann architecture is like talking about the difference between a steam engine and a gasoline engine while Turing was talking about the laws of thermodynamics. *> It seems clear to me that Turing Machines, Van Neumann Machines and GPUs > are just implementations of something which is purely abstract -- > computation.* > Turing Machines are in a more fundamental category than the other two. All Van Neumann Machines and GPUs are Turing Machines but not all Turing Machines are Van Neumann Machines or GPUs. *> You insist that nobody has been able to produce a computer without using > matter. I agree.
