I keep coming back to this sense that technological advancement has just sort of hit a wall. In the last 20 years we've seen processing power become cheaper and not much else. This has given us new, arguably shittier forms of mass media, but nothing really different. And notably it's given us a parade of bullshit and bubbles pretending to be the Next Big Thing. The VR dream keeps recurring in various forms, 3D displays, 3D printing, blockchain, the gig economy, "AI," almost everything in the "green" apocalypse mitigation field, and now I guess cold fusion.
The only thing I can see as having real potential is quantum computing, because scaling it up would obsolete fundamental security features of almost every computer on the planet, but that's still in the early experimental phase and the bullshit artists haven't figured out how to market it widely.
