> We're unlikely to see high-pressure H2S lines running through residential neighborhoods any time soon. That wouldn't be necessary to make the technology commercially viable, though. Forty years ago Cray sold over eighty Cray-1s, initially priced at the equivalent of about USD 35 million today, and there were probably much larger numbers of mainframes, scientific computers like the PDP-10 and so on that could go for about $1m in today's money. If anyone today could offer much faster single-core execution speed at comparable costs I'm sure they could sell similar numbers of systems, especially since the infrastructure for remote timesharing and job execution is much better and more widespread nowadays. It's the titanic pressures needed to keep the material solid at all that make the idea infeasible at present I assume (how would you even whittle a circuit out of it?)
