But this is not solving the problem, it's just reducing it. My analogy with compilation of C++ is that noone SHOULD expect it to be "solved", because it's a natural consequence of how the compilation works. They may improve e.g. incremental compilation to reduce compile times, but it's just not a problem that can be "solved". Similarly with Julia and latency.
