> I don’t see Julia a good replacement of Python. Julia has a long startup time. When you use a large package like Bio.jl, Julia may take 30 seconds to compile the code, longer than the actual running time of your scripts. You may not feel it is fast in practice. Actually in my benchmark, Julia is not really as fast as other languages, either. Probably my Julia implementations here will get most slaps. I have seen quite a few you-are-holding-the-phone-wrong type of responses from Julia supporters. Also importantly, the Julia developers do not value backward compatibility. There may be a python2-to-3 like transition in several years if they still hold their views by then. I wouldn’t take the risk.
