With the death of Flash it's not just the vector based screen on its way out (that's been on the way out ever since Evans and Sutherland invented the framestore at the start of the 1970's) but also vector based graphics (or at least one commercial application). However, one could see the memory mapped images as being akin to sampled sounds and therefore vector (mathematically modelled) graphics as similar to subtractive or generative synthesis - and in the world of electronic sound we have seen that whilst the sampler initlly seemed to supersede the synthesiser in reality that didn't happen. The synthesiser came back into fashion and manufacturers started shipping them again. So you never know, the CRT could make a come back in another form - perhaps with the new family of laser scanning projectors companies like Casio are pioneering? The principle is the same as the CRT.
