As businesses only exist to make money, a money-losing business doesn't stay in business.

In the 70s, it was cheaper to use iron instead of aluminium for engine blocks. And cheaper to throw CCs at the resultant weight than to make the engines more fuel efficient. But then, oil was $3/barrel, now $115/barrel.

Have you heard the expression. Costs the earth?

My machine is currently generating a 250M element dataset. My first attempt would have run for 57 days. I abandoned it. My second attempt would have run for 4 days. A couple of optimisations and I got that down to 20 hours. Total time expenditure was maybe 6 hours.

Or I could have bought 70 machines, plus clustering software with shared memory capability. You do the math.
