Here's some reality surrounding certain socioeconomic fads, including the "technology bubbles" we'll see intermittently for the next 100+ years since technology is becoming the only economic force that really matters. The visible winners and value-harvesters are usually idiots who got lucky. We look at what they're doing and we say, "When the tide goes out, those lucky, no-talent assclowns will have left us with nothing." The people getting invited to the "hip" parties and the most exclusive events at SxSW are generally what you'd expect in the era of social douchebaggery: people who are too busy partying to get real work done.
Okay, okay; but something else happens, and there's a silver lining here. While all the hipster douchewizards scramble for visibility and credit and the image of "A-player" status, progress still continues. Somewhere under all that smoke are the invisible people who are the real A-players, usually taking home a "B" or "C" outcome. You rarely hear their names (sometimes you do, but there are too many of them for more than 0.1% of them to achieve real notability) but they're the ones doing actual work and building great things. And in 2025, when all the "social media" robber barons are either washed-up billionaires or washed-up and penniless, the work that the real A players are doing right now will still matter. The applications of their work may have died out, but their work will still be around and people will be putting the ideas to better use.
