TFA doesn't even propose a non-serial programming paradigm that programmers can easily learn. I suppose array languages, maybe? It's hard to imagine a CPU architecture where there's no branches, or minimal branches, or a language that greatly minimizes them yet can be used to implement the sorts of software we're fond of. A lot of what we do with computers is highly parallel, but also highly serial with lots of logic -- is that the fault of C, or is that natural and C is just a scapegoat? My money is on the latter.
