Java moves a lot slower so I don't think it will obsoletes Go.

If anything, if Loom is great, then it will keep Go on its toes and hopefully Go will also evolved due to external pressure.

I beg to differ. Go has been moving at a glacial pace. Generics took forever to implement, aren't even feature complete (no type parameters on methods), and have no integration with the standard lib. Meanwhile Java is adding lots of new features and versions at a quick pace.
