I've tried to learn rust of the longest time but failed, it's not the community that is the problem but the language itself. It is far from aesthetically pleasing, a child of perl and c++ meta template programming that inherited the worst traits of both.
Go and Python are my current preference, and C being an old soul mate.
If I understand it correctly, their target is projects like the recent pgrust (PostgreSQL in rust) which are full conversions of projects that no-one else will ever use. It's just noise.
I am not a believer, but pray that whichever $DEITY is watching over Donald Knuth allows him a healthy and long life to reach the achievement of finishing volume 7.
IMHO there is little point of these conversion projects. It screams of "look at me, see what I made" and when the attention goes down a little nothing was ever pushed to the repo ever again.
Perhaps I am out of touch, but a project with author/s that have passion for every line, function and purpose, feels more real and worth my trust to spend time using it.
I am 100% certain, that if you go to a Ferrari dealer and buy one of their cars, they will clearly inform you of their rules.
Of course you can have a friend to buy it for you, but again, it's Ferraris choice who they want to conduct business with as long as they follow the laws to the letter. Their car is their brand and they want to protect it.
