> Ouch, just spent this month learning Angular

I've found that no knowledge I've gained from learning technology/framework/language etc has ever gone to waste.

Somewhere down the line, the insights gained previously come in really handy or even make something that I thought wasn't possible, realizable.

Looks like your learning is still valid for another couple years - this isn't being released any time soon, and in fact won't run in most of today's browsers.

Two years in internet-time is a long time! For all you know, civilisation as we know it will have ceased by then.
