I too am very interested in this model. The Linux kernel supports up to 4,096 cores [1] on a single machine. In practice, you can rent a c7a.metal-48xl [2] instance on AWS EC2 with 192 vCPU cores. As for programming models, I personally find the Java Streams API [3] extremely versatile for many programming workloads. It effectively gives a linear speedup on serial streams for free (with some caveats). If you need something more sophisticated, you can look into OpenMP [4], an API for shared-memory parallelization.

I agree it is time for some new ideas in this space.
