What I do when a new tech hype comes along, is allocate myself some time to it. Ok, Webpack? Let me give myself three days (around 20 hours) to check it out. If I don't understand it at first, keep pushing. If after 20 hours, I still don't get it, abandon it and move on.
Of course, 20 hours is just an estimate. If after a day, I feel like some magic has taken place (like what Backbone.js did to me), I'm hooked.
And yes, definitely gravitate towards a galaxy. Sometimes galaxies do merge and you will reap the benefits :)
I'm 38, programming for 15 years. And I still love coding and doing systems stuff.
