We need to go from it being special to open source code for a paper to making it almost seamless to interact with a presented idea, to try it in new contexts, to build upon it, and, yes, to falsify it.

When we introduce examples into an article we do so to make it easier to understand our message, but this opens us up to criticism of cherry picking our examples. We take a first step by allowing readers to choose from a set of examples, but real progress is open sourcing the code behind each diagram, and making it seamless for readers to run.

If you primarily care about finding truth, then you don't only need to make reproduction and falsification possible, you need to make it easy.
