Speaking as someone who was born blind Braille may not be worth using if you went blind later in life. I was forced to use it heavily until about 10 or 11 in spite of the fact that I wanted to use text to speech since it's quicker. It was totally worth it since it gave me a basic literacy foundation that enables me to type out sentences like these and be able to spell well enough that less then 1/5 of everything I type has to be corrected with Spellcheck. I have an 18-year-old braille display I got in school when I started programming more. It still works but I only use it once a month if that. I do everything with text to speech. The only time it was really useful was when I was doing assembly programming and had to look at hex values in a debugger. If you go blind later in life it may be pretty easy to avoid learning anything but enough braille to read signs for room numbers and bathrooms and do just fine.
