Well, all I can say that is "definite" is that the above statement is
definitely garbage. ;-)<br>

Until you understand what is involved in the mechanisms of
intelligence, you are in no position to make such a definitive
statement.<br>

Are you sure? Given the known average speed and other performance
characteristics of ordinary PCs (and their OS) and any particular model
of an AGI it should be quite possible to say pretty definitively
whether that model can be usefully realized on that hardware. This is
an engineering task that does not require deep definitive knowledge of
what mechanisms are capable of producing intelligence.<br>

Well, let me answer by throwing the question back to you: in your
comment you said ".... and any particular model of an AGI", which is
equivalent to my saying "... until you understand what is involved in
the mechanisms of intelligence".<br>
<br>
Both of these statements imply that *given* a particular model of
intelligence that is known to work, you can talk about whether that
will be implementable on a PC, but that is not the same as declaring
that no future implementation will run on a PC.<br>
<br>
There are no known viable models of the structure of an AGI at the
moment, so my main point is that definitive statements about the
implementation needs of a future theory are, well, kinda premature.<br>
<br>
In addition, my own calculations (given long ago in other posts on the
topic) indicate that an architecture involving the class of cognitive
system models that I work with (crudely speaking, relaxation systems in
which there is a correspondence between cortical columns and relaxation
cells) would be implementable on a machine that is within about one
order of magnitude of the power of a PC. (To be more precise: the
power of the graphics coprocessor in a PC, since that would have more
appropriate parallelism and granularity). <br>
<br>
That is a very rough calculation, but it does mean that these
declarations that I hear, to the effect that we will need one PC per
neuron minimum (or similar), or statements such as Eugen's, above, are
profoundly useless and misleading.<br>
