You do have a lot to learn. So do I. So do we all. The universe of things that get posted to HN are too large for one person to master - it's why I still visit. Lots of good suggestions here, but one I don't see is to simply narrow your scope. Choose one thing, make it your own. Keep it small, and soon you will find you can converse with that niche's recognized experts. Iterate on that theme and you will constantly expand your scope - in a few years you'll look back and realize you know a lot of things. Tech could stand to take a cue from other disciplines. To his peers, a physicist is not just a physicist - she's nuclear physicist with a focus in particles, or a biophysicist with a focus in computational molecular modeling. Tech has the same de facto specialization, we're just changing too fast for the taxonomy to stabilize and become vernacular.
