Go won't survive
Ever since the debacle that was AngularJS (specifically, they way they tossed v1 in the garbage and came out with v2 that was completely different), I have been distrustful of any language that Google might come out with. Google treats its languages with the same distaste as it treats all its other products. ie: badly. I don't have the time to learn an entirely new language every couple weeks cause the previous widget isn't cool anymore.
Their entire collective workforce has a worse attention span than a single squirrel hopped up on amphetamines.
