Alan Kay on the Meaning of “Object-Oriented Programming” (2003)

Rather the opposite. Almost all HPC (high-performance computing) systems use message passing and not shared memory. The fastest and imho best unix-like kernel L4 is entirely MP based.

So if you want to embrace high performance (and concurrent), go message passing. Alan Kay's favor of late binding does not help performance, as method lookup at run-time dominates the cost then, but the fast systems are early bound, i.e. typed.

Well, you are discounting CUDA, which has been seen as suited for many tasks when compared to MPI. Of course, you can use MPI and CUDA together (people are working on that), which you then have messaging between nodes and shared memory (via GPU-style SIMD) within.

Of course, you are probably referring to NUMA, but people still actually use that.

Pure OO isn't very much desired in the HPC world, but then neither is pure FP.
