I think this is not true, many of us (including myself) were really intrigued by Julia and really wanted to like it, but came away a bit underwhelmed.
It certainly has some neat ideas and people do very interesting stuff with it. That said it is certainly not the panacea of "write code which is as easy as python but gets you the speed of C".
What is causing the current (small) backlash is the community being so strongly fanboyish and are still selling this uncritical view. Compared Julia fans, Rust proponents sound like they hate their language.
The advocacy is becoming quite off putting.
