New POSIX OSes won't take off in a meaningful way either (whatever 'meaningful' means). It's nothing to do with it being POSIX or not, it's just difficult to get traction for a new OS. Linux faced exactly the same issue when it was released. But why do you need it to take off in a meaningful way? Open Source software doesn't need a particular market share to keep going, it just needs a certain absolute number of people (which differs depending on the software). Is having a small committed core of users not enough for you? If your research is truly useful then that number will grow over time. Unless you're talking about a commercial OS, in which case Microsoft is your obstacle, not POSIX. Good luck with that.
