It also seems to me that even if you accept all of those things as fact and are OK with them, say in an O&G HPC workload where you cool the DC, run for a few days/weeks and then go offline to fix issues until the next run, isn't the amount of energy and cost required way higher than just having more compute resources? Ultimately its just dollars per compute and it seems highly dubious to me that supercooling your components, even if you accept high failure rates and long lead times, is going to move that needle in a positive direction.
