> Do folks have practical examples that would make development of alternative computational models worth it? This is the question to ask people when they say "the von Neumann architecture is a bottleneck". That being said, I think a strong contender is the dataflow computing model. The advent of the GPU already heavily punishes control flow, and workloads are being increasingly constrained, hence the possibility of a real world success for dataflow machines.
