Great to see everything is quiet again around here

If Tau is ready - someday, when it is ready - I presume the work only begins. As a community. What is a smart roadmap to:
1) Get educated in the right fields to be able to use/program Tau? What should neccesarily be learned already?
2) How to get some experience, before Tau's ready, that is useful? What language? Or knowledge? Or skills?
Basically: What's is relevant to have done to be prepared once this network is up and running and Tau needs some serious usecases and testing?
As I mentioned here. I am still wondering what needs to be done once Tau is up and running. To have tau make use of semantics we probably need a lot of useable contextual data that allows tau to interpret transactions and (business)logic in a meaningful, automated manner. Is there a structure, ontology, nomenclature or some sort of thesaurus we could build already, as a community, to come prepared?
