CXL will provide exciting opportunities in marketing, buzzword-generation, consulting, and certification programs!

CXL-attached RAM could accelerate multi-user timesharing systems, which I haven't seen in use since the mid-1990s.

Seriously, though ... if running multiple VMs on a single CPU is the new timesharing, CXL-attached RAM could allow more VMs per-CPU, but you could do the same by adding more conventional RAM to the system. Whether or not the CXL gear would be cost/performance-effective for this, vs just buying more nodes with their own CPU and dedicated RAM, is something we won't know until we have CXL hardware price info and benchmark results.
