yes, of course. the same non-consumer-computing-intuitive logic applies to
purchasing decisions for beowulf clusters.

arse.
and if everybody does that, then no matter the performance/watt nobody
"wins". in fact a case could be made that everybody "loses".
my biggest concern here is that the inherent "arms race" results in very
few players being able to create bitcoin mining ASICs *at all*.
i mentioned earlier that geometry costs are an exponential scale. 3nm must
be somewhere around USD 16 million for production masks.
if there are only a few players that leaves the entirety of bitcoin open to
hardware backdoors.
