Bonus points for a local HTTP service that provides an optional GitHub-like experience in the browser, with comments/ branch reviews/etc. federated through emailed messages (and represented as commits on meta-repos).
With that data model, the primary remaining challenge would be setting up repos on a new machine -- perhaps BitTorrent could help :)
Human agency tends to normalize on the brands with biggest marketing budget who collude with politicians to create a moat for themselves. There’s your real problem.
Of course none of the propaganda research that made its way from military after world wars to corporate advertising and marketing college programs has any influence on lizard brains. No sir.*
