There is a cautionary tale here for anyone who wants to write great software. Solaris is great software, and yet I wouldn't want to run it because I wouldn't want to hire for it. OSes are complex enough that you want specialists who "dwell" in the space (as opposed to casual things, like libraries), and the community is just too small. (That said, sometimes teams pick the outlier and win - WhatsApp and Erlang come to mind. But this is really rare, I think.)
