Mmm ... he may be right, but I do not like his historical references which seem 
to conflate engineering and economics.  Better to refer to the improvement in 
magnets or something similar.  But, I like the speed of sound reference because 
it suggests that there is a Moore's Law barrier to be broken.  There is a lot of 
talk about "walls" these days ... the memory wall, the power wall, ... but we with 
respect compute power we have a ways to go before we reach the Bremermann Limit.
