alt Hacker NewsGGPs question doesn't make sense though. What does it mean for a technology to "come out".
Also what does three prove? Is three supposed to be a benchmark of some kind?
I would wager every year there are dozens, probably hundreds, of novel technologies being successfully commercialized. The rate is exponentially increasing.
New procedural generation methods for designing parking garages.
New manufacturing approaches for fuselage assembly of aircraft.
New cold-rolled steel shaping and folding methods.
New solid state battery assembly methods.
New drug discovery and testing methods.
New mineral refinement processes.
New logistics routing software.
New heat pump designs.
New robotics actuators.
See what I mean?
Great list, and most of those don't involve big tech. I think what your list illustrates is that progress is being made, but it requires deep domain expertise.
