According to Yaron Minsky (Jane Street Capital), yes: "One of the things we noticed very quickly when we started hiring people to program in OCaml was that the average quality of applicants we saw was much higher than what we saw when trying to hire, say, Java programmers. It’s not that there are not really talented Java programmers out there, there are. It is just that for us, finding them was much harder. The density of bright people in the OCaml community is impressive and it shows up in hiring, when reading the OCaml mailing list, and when reading the software written by people in the community. That pool of talent is probably the single best thing about OCaml from our point of view".
