From what I can tell, this language builds on the learnings of Eve[1] without any investor money (Eve ran out of funding[2]). The state of the project is questionable, as can be seen by the dates on this page. Their active repository seems to be on GitLab[3] despite the links on the landing and in the README. It doesn't look like it has a lot of contributors or even people observing it, so I thought the HN crowd might want to look into this. I tried to find a Discord server or something like that, but it looks like they just communicate over email, so I have no clue as to what use they're making of their potential community involvement.
