Rust has a huge online community but has not (yet) had a massive industry adoption. GP was asking how that can be achieved.
Amazon, Microsoft, Google, Dropbox, Cloudflare, Meta. This is a list of companies I could think of quickly, that don't just "use Rust" they are "heavily invested in Rust".
If this isn't "massive industry adoption", its not clear what is.
A) Get lucky.
B) Be the only choice.
C) Get a massive corporation to back you.
Otherwise you can't ride the network effect to the fullest.
