It's good.
I have significant issues with the core argument, but mostly due to it's naïveté.
It does not address the issue that there are numerous, hmm, micro-languages. Say one invented spontaneously between twins that only the twins and say a couple grad students (maybe) will ever be fluent. The twins language may be incredible but it is useless to order a big mac.
Can two autistic folk each with their own totally valid non-verbal language ever communicate?
The world is getting so specialized, perhaps with tools some very smart folks cut off due to neurological, er differences, will become dynamic members of the greater society.
I really liked the view down the slinky, good thing that it was not a full 9 minutes of just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. just that. (wow, doesn't it feel good typing just that ;-)
