I see what you say, but have to nitpick this: “Java a while back had the problem that when GC would run, the application would freeze for a bit due to how the GC worked” — Java has pretty much always had the very best garbage collector available, though it was historically mostly interested in throughput-oriented workloads (due to its wide-spread usage in server software). Other platforms may not have had it as noticeable, but they just probably traded off throughput for better latency (e.g. Go still does it, by blocking threads that would allocate when it can’t “make sure” it will be able to keep up).
