I think this is also a paradigm problem. Modern chipset advancements are at the crossroads of power vs. cooling. The logical extension of that fight is greater power and cooling requirements in the DC which it is not necessarily equipped to provide by default.
This is why I thought what Colovore did was pretty smart- they built liquid cooling into all of their racks. They are literally the densest datacenter I've found that actually allows people to colo with them (I'm sure there's plenty of companies who own their own datacenters that might be denser), but even with their systems you'd only be able to fit two of the Cerebras systems in a single rack (and you wouldn't be able to power both up 100% at the same time).
