This makes me wonder... in an age where we have tools to open-source and crowdsource software programming, would it be possible to crowd-source the creation of a new language? It could then be refactored regularly (with new major versions published every X years), the source of truth would be the main branch of the repo, and the role that an Academy usually assumes (approving changes to a language) would be given to contributors.
I suspect that a language created by a common effort from a thousand brains would be simpler and more optimized than one invented by a single person in the late 19th century, no matter how hard that person worked on it.
