Agreed whole-heartedly, though maybe the advent of liquid metal 3D printing will be a new innovation that will change the world? I didn't think much of the plastic layering jobs (I have no need for prototyping, but appreciate they are very useful for others), but printing in metal without the layers? When that is at the pro-sumer level, I think we'll have another revolution on our hands, comparable with the internet or smart-phones.
So maybe the good stuff is still happening, just buried in all the cr@p? Or maybe I'm just another old guy who's out of touch!
