We have chips in our watches that are more powerful than a super computer from a few decades ago, and yet after all this time we still haven't really improved readibility from 1970s terminals. I still have to battle to find a serious manufacturer that makes flicker free panels, I still have to battle to find monitors with a smooth refresh rate and pleasing accurate colors. Currently there are no displays that allow me to read text for a prolonged period of time. This seems such a no brainer thing to improve, especially since most tech workers spend their days reading and writing emails, spreadsheets, documents, code, etc.
