Technically I agree, but nowadays with 5G+Edge computing, where low latency application requirements are essential, there will be other performance constraints not tackled by Java that needs new solutions. Previous JVM attempts mostly focused on "write once, run anywhere". But now, "anywhere" means "anywhere and quickly" :)
