Is it because Chuck Moore said so and people are afarid to go 64 bit , or is it a more technical thing like power consumption? I think if designed well with todays minuaturised memory circuits a 64 bit CPU could easily compete with a 16 bit CPU (speed , size , power consumption) and seriously out perform it.

I've never really understood why the number of bits has to be a power of 
2. Early computers had all sorts of strange word widths. The first 
computer I worked with was 24 bits with 18 bit addresses.
