computational transparency and increasing computational reproducibility in coming years. We imagine that PSEs will continue to be very popular and that authors will increasingly share their scripts and data, if only to attract readership. Specialized platforms like Clawpack and DUNE will come to be seen as standard platforms for whole research communities, who will naturally then be able to reproduce work in those areas. We expect that as the use of cloud computing grows and workflows become more complex, researchers will increasingly document and share the workflows that produce their most ambitious results. We expect that code will be developed on common platforms and will be stored in the cloud, enabling the code to run for many years after publication. We expect that over the next two decades such practices will become standard and will be based on tools of the kind discussed in this article. The direction of increasing transparency and increasing sharing seem clear, but it is still unclear which combinations of tools and approaches will come to be standard.
