The problem is that 360°/VR is the only way forward for development of video technology. We've hit a wall of physical limitations of the wetware, and basically without the hope of success of 360°/VR we could just stop
development of anything video related as nearly any improvement on the other aspects would simply be useless.
We've still a few things to accomplish,
the next development in TVs will be extending the colour range (RGB LEDs currently don't accurately display actual colours)
Then there is the refresh rate, apparently gamers can tell the difference between 25hz and 100hz
The blurring of video is a tricky one, that's a vast amount of data to shift and hope your display technology is going to react accordingly
Everything we see is mostly reflected light, everything on a TV is a light source, I'd imagine the perception of each is different, I don't know how we'd compensate for the difference.
I'd like to see manufacturers simply stop putting loudspeakers into TV's - they are now too thin to do the job adequately, yet people persist in ruining their experience by putting up with tinny sound. Although I'd also like to see hi-fi manufacturers stop making tiny loudspeakers and pretending physics is trumped by their marketing department.
