Lucia, you're 100% right. If Deaf culture didn't disappear when HAs were introduced, then it won't disappear now that CIs are used.
I have NO beef whatsoever with people getting implanted who have NO or very little benifit from HAs.
If someone posted here that they weren't getting all that much benifit from HA, after extensive trying out HAs, then I'd strongly enocourage them to get CI.
But it does seem like there's the....not trendy factor.....but more like......for example back in the 90's digital aids were being pushed as the next BIG THING. I see that happening with CIs, now that the implantation criteria has been loosened a bit.
