I'm afraid something like that is already happening.
When I first started losing my sight I was taught Braille by this blind guy at the local library. I was told by many people that I did not need braille. The guy was also teaching Braille to a fully sighted girl guide. I wonder if anyone told her she didn't need braille either.
But it's true, on both sides of the atlantic blind children are being denied braille in favor of print on computers with speech synthesisers or large print if they've got any residual sight. I signed a petition recently by a mother of a blind son who's school was refusing to provide any braille. From what I've read similar things are happening in USA. I think it's because more blind children are being intergrated into regular schools instead of schools for the blind. I think all Blind and partially sighted children should learn braille. Even if they can see enough to read print. I mean what's wrong with learning both.
