Fact: An well-equipped Raspberry Pi 4 has more memory, more compute power, more storage and vastly faster networking than the Cray supercomputer I worked with at a major oil company in the 1990's! With the exception of the craziness around click-tracking (web ads and marketing have warped compute use even more than crypto), the data required to run even enterprise-scale businesses today is not really all that large.

For almost all purposes, we don't really need thousands of containers running on unimaginably fast computers, coordinated by AI-driven automation systems. What we need is software that is not morbidly obese.

I mean a single V100 GPU (~= 100 TFLOPS) has FLOPS throughputs similar to top end mid-00's supercomputers like Blue Gene, at least superficially. And you can squeeze like 4+ in a 1U if you have enough cooling and power.
