Agreed, that's why I think the GraphBLAS would be such a great fit for this hardware. The ecosystem is growing pretty fast. There are, for example Python bindings, you can do sparse 'A @ B' on millions of elements in parall

This thing needs a GraphBLAS[1] implementation yesterday. 100 billion edge graphs and up are the new norm. This monster could smoke the competition if the implementation was tuned right! [1] http://graphblas.org

I think it's a good article, and reading some of the past posts in this blog I see the author is a fan of Judea Pearl's causal do-calculus, as am I, so that was also a good read. The article missed an interesting new area of resea
