I don't know. I wish that someone like MS would take this and really spend some big dollars on it. Mozilla is doing a great job but better collaboration between the vendors would be extremely beneficial and really increase its development. That's my hope anyway.
I mean, yeah, that would be amazing for the ecosystem. Still! I hope some small guy comes and makes something awesome with it, esp. w.r.t AI, which Rust seems sort of perfect for. As much potential as the Amazon-Microsoft-Google-Facebook-Acme Co. collab has, I'm not convinced that they aren't going to use it only to build dull chat bots and give us marginally more relevant ads.
