Earlier quoted context omitted.
You're not disabled yet . But you may want to care about this before your eyesight, motor accuracy, etc. start failing. It's not some big "disabled/not" switch - setting the font 1pt higher is accessibility, changing the colours is accessibility, being able to tab through fields consistently is accessibility, etc.
The idea that I might eventually become disabled still doesn't make it an essential feature. Disabled users are not a significant portion of the userbase of most software. Accessibility is an essential feature for a text editor in the same way that Linux support is an essential feature for Fortnite.
Have I got news for you. https://www.disabled-world.com/disability/statistics/
> Currently, around 10% of the world's population, or roughly 650 million people, live with a disability.
> In countries with life expectancies over 70 years of age, people spend on average about 8 years, or 11.5 percent of their life span, living with disabilities.
Sure, not all of the disabilities will apply to using an editor. But disabilities overall are very common. A significant proportion of users of anything are disabled in some way - it just may not be obviously visible.
