Dumb, aggressive promotion is characteristic of "trendy hipster projects" usually abandoned once the "cred" harvest is finished, and people involved go on.
I used to advertise my worth in how good my C++ is. Until I had a dumb after free error after git merging two adjacent line in the wrong order. A simple vector push done after capturing vector.begin instead of before. Nobody saw that in code review. Even reviews from C++ experts at the company. Of course it took 6 months until the first segfault. Invalidating 6 months of work. Rust would have not compiled. As simple as that.
Now imagine if you could write code without living in fear of making everything blow up because of a single moment of weakness. That's Rust for me.
What kind of system was this where a bug would literally invalidate all results from the moment it was introduced?
And it's not going to stop. That's the thing about the memory safety argument; the people making it have an endless supply of ammunition, resupplied daily.
