Referring to start-up latency, the author asserts:

Citation need. Today, the Julia compiler runs in JIT mode. But there is nothing preventing it from being ahead-of-time compiled (indeed, some work is going behind the scenes to make this happen). There is also an interpreter for Julia. I don't see latency or large memory footprints as being "fundamentally unsolvable".
