>>105761621Too much up-front cost to start making them again. I imagine the electronics would be no problem but all the factories making the actual CRTs themselves are gone and building a new one from the ground up would be extremely expensive so it's probably not worth it.
I think you're overestimating the popularity too, CRTs are good for retro things from the eras where CRTs were actually in use and even then the "CRT magic" is mostly limited to the very low res 15kHz you got on TV sets. PC CRT monitors have much less of a "distinctive" look to them and the only advantage they really have over modern screens is motion representation, everything else from brightness, static contrast, color space, sharpness, geometry, refresh rate and so on are far superior on modern screens.
So if you're not going to use a CRT for old shit from its era, it's going to be way outdated and getting them up to par with modern screens in all the other categories would likely require a whole lot of R&D as well.
