Briefly Talked with John Carmack at Quakecon about Julia

[ericphanson]

I think this remark from another thread is relevant:

@johnmyleswhite

Julia is almost surely not going to displace Python for ML because Python for ML is actually C++ for ML. As such, replacing the Python ML frameworks requires Julia to be dramatically better than C++, not Python.

If most the execution time takes place in kernels written in a fast language, then Julia is likely not anywhere near 100x faster. In fact, if those kernels happen to be more optimized, then the Julia version might be slower.
