Your comment reminded me of the talks on the issue of information display for Matplotlib[0][1]. I think a lot of design is done without awareness of accessibility and this is more broadly a cultural thing than a technical thing. The situation can be improved both by technical means (OS or hardware awareness) as well as by our collective education about what kinds of issues designs should consider. Typically, designs become better when they account for accessibility, but it is oftentimes seen as a hurdle when a designer or developer has not heard about the issues and also is not equipped with tools to handle them. Having good tools is helpful here. The situation seems to be improving, but it will take time.

When I was in elementary school, you had to special order large print text books, audio books were available, but required special tapes & players. A portable CCTV could be used to magnify small print. All of this equipment was specialized, expensive and hard to come by for most people. All of this has been replaced by features built into my phone. Special shoutouts to the "Zoom" app on iOS, that thing has color filters for people with color sensitivity issues and enhanced text rendering for small print (unfortunately, it's buggy and crashes sometimes), but it is much better than littering my camera roll with random pictures of menus or the bottom of routers just so I can zoom in on some numbers.
