The article seems to reference having external AI etc accelerators colocated with the RAM they use, but then tied to a host machine via CXL. So that makes a certain amount of sense. Latency sensitive stuff happens co-located with the RAM, and then you just take advantage of throughput back to the host.

I'm personally now imagining a specialized database appliance which takes the role of the whole of the pager and buffer pool management from a DB (or KV store or whatever); a physical box which ties secondary storage arrays + large quantities of RAM + buffer pool mgmt firmware together on a box, then connect to host system via CXL. Host system does query planning end execution and everything else...

Is anybody doing this? Does anybody want to found a startup with me to do this? <sips more and more coffee...>
