That's why I wish lojban would take off, although I know it never will.
summary of lojban I posted elsewhere:
I’m learning lojban with my girlfriend right now for many reasons, I think this language would be absolutely insanely wonderful for autistics, for a few reasons
It’s syntactically unambiguous, this means every sentence only has one meaning
Attitudinals, at the start of your sentence, you actually state the tone it is meant to be interpreted in (you can see how that could be massive for autistic people alone)
Text has the exact same meaning as the spoken language: Y’know how in english, you have to write punctuation marks? in lojban, those are words, meaning when combined with attitudinals, the written language has feature parity with the spoken language.
