Do you remember back in the '90s, when high-definition TVs first started to become popular? Seeing that HD for the first time, the sharpness seemed almost impossible compared to existing technology. But this year, several top tech companies showed off 8K screens with 16-times as many pixels as those old 1080p HD TVs. For me, seeing these new super sharp TVs at the Consumer Electronics Show (CES) felt like the first time all over again.
