Though he is talking all fluff and nonsense (meaning he isn't saying anything which he can
possibly define or
possibly understands but only relies upon the perceptions of the
words of the listeners.
My following comment is just about '
simulated mind' not 'simulated worlds which is he also talking about.
The idea of
simulated mind is absurd; that is in the end it is meaningless; it can't be possibly proved or rejected or put to test.
If mind is 1) simulated (i.e. there is a clear distinction of mind and body- which is a very old question from antiquity) and 2) planted (this new idea comes from the computer lingo of 'installation' process -
recall the movie Matrix) then the observations and sensation are also
essentially simulated and we are not aware of any 'reality' i.e. the reality is just our reaction or output and again the perception of our reaction is just a simulation and so on.
Thus the outcome of the idea of simulated mind is to give up
reality to 'the individual' and 'all of his interaction/observation' and in return no new 'knowledge' is gained except for the fluff material for science fiction.
Why to be be content with simulation (and be fascinated with computer lingo), why not the all the data is transplanted and the function of mind is not 'the calculation' but just 'the presentation' (logically the idea is the same, if the software writer was about perfect).
** there is vast literature regarding mind-body problem in biological sciences and perhaps would not support this guy and the same goes for the physics of
simulated multi-universe.
