I would love to see modern CRTs but we have to be honest with ourselves about the negative environmental side with their lead components. Perhaps we could build a more environmentally friendly CRT with our processes nowadays.
It’ll be very niche gadget so who cares about environment.
You'd think that about mechanical keyboards too, but there you go.
Mechanical keyboards are a small niche. I would be suprised if they make up more than 0.5% of the keyboards in use today.
In addition to this, once OLED monitors for PCs (or similar) become commonplace, a lot of the complaints I had about LCD/LED are no longer relevant. My LG CX looks absolutely stunning, and the input lag is unnoticable.
