Let us make it easier, so that we can see whether and where a
disagreement exists:

- Beyond the level of universal computation, there is no other
"threshold" which may be required for any device to perform any given
computation, the difference obviously being in the relative
performance of different devices engaged in different tasks;

- An anthropomorphic AGI is a computation process of one kind or another;

- A contemporary PC is a universal computation device.

Hence, a contemporary PC, exactly as a Turing machine or a cellular
automaton of the right kind, is in principle capable of running an


Educated guess, but by all means not a fact:

Contemporary PCs seems unlikely to perform very well in any such task,
including in comparison with human brains, so that you for a
persuasive AGI might have to wait for aeons to get a reply in a
Turing-test interaction.
