I hope (reatively immature) solutions like this will not be used as an excuse to remove accessible infrastructure from the world (e.g. captions at the cinema, live subtitles at the theatre, text displays on public transport).
There is a huge population group that I am hoping will demand and make accessibility much more refined. Everything from the size of text to lighting levels to subtitles
Many countries have aging populations, so the proportion of people who have a personal reason to care about issues like sight degeneration is going to increase significantly over time.
