I'm not sure what you mean. Certainly, if your invention is good enough, I'm sure you will be able to find some success, even if you don't change Deaf culture as a whole.

But to your point, I meant that cultures do change; willingly or unwillingly, when faced with disruptive and effective technology. The strange thing is; they sometimes willingly change for the worse.
