Library support is a big deal, and obviously a new programming language won't have a whole lot of that. That issue gets a lot smaller, if the language allows an easy way to abstract away a lot of those issues, making it quick and easy to deal with whatever you'd look for a library for. If your main goal is to find lots of library support, this new language won't appeal to you.

I'm reserving judgement until I actually see it. Maybe it's a great, fun to use language that gives significant performance advantages over other high level languages. If I need half the servers, that could be a big win. If threading and concurrency are abstracted away in a way that's performant and I don't have to worry about it, that's a big win. I don't know what it will be, but if it's useful it's useful. Seems a bit silly to judge it before it's out, especially criticizing it simply for being a "new" language.
