There are many benefits. For example great exception handling. We’re paying very little performance cost for having the conveniences of a managed runtime. Let me flip it, we don’t want unmanaged runtimes, we are forced to run in native, because we need the absolute highest performance in some cases. If the hardware could understand Java bytecode and provide all other JVM facilities, that would have been spectacular. Unfortunately that would be very expensive and pointless as we’ve demonstrated over the decades. If anything we’re moving towards reduced instruction set chips - ARM, RISC-V. And so in many ways the complexity you see is well understood by the folks that have to understand it, it’s well managed, it’s worth it and it’s not at all a performance problem worth tackling.
