Considering that Matlab, which is supposed to be a stable platform, seems about as buggy as Julia with a lot of regressions, API changes, and new bugs every release, I, too, prefer Julia, as it's not only a nicer language with better programmer and execution efficiency, but it's also open source.

I'd rather try to fix a bug in some undocumented codebase than wait 6 months for a new black box.
