You have to take all this with a mountain of salt. Boosterism is the norm in our space, sadly. If one devotes time to learning a technology it is personally advantageous if that technology takes off. Hence you get this kind of "My programming language and community are already wonderfully perfect and kick more goals than there are nets to kick into" stuff. And the worse, yet related utter rubbish we see all the time. "C is a virus", "Perl is line noise", "failure to use JVM style garbage collection is idiotic and unsafe". etc etc. You can swap out those languages and swap in any others you like. It's pervasive and that is a shame.
This is the same kind of thing even if less stomach turning than the negative crud. It's pretty crappy and doesn't really belong here any more than Oracle and IBM global services adverts do. It is not anything like objective and in any sensible assessment of Rust should be roundly ignored. Just like big consulting firm whitepaper "Are you enterprise ready!?!?!"
All the very best to Rust hackers, may you achieve your technical goals in both your design and implementations and have loads of fun on the way!
