In some ways yes. But not entirely. There are still very large groups of people who insist on still using voice phone/calls... Most notably recruiters and hiring managers. Even when you TELL them that you don't have/use voice phone in email, the very next email they send will say "Please send me your contact number" or "Please call me".
D'OH!
I am born deaf, use hearing aids(with terrible speech discrim), know sign, use VRS with vco (my expressive signing is a little rusty and receptive fingerspelling sucks) and YES hearing does matter in some circle no matter how much I state the opposite.
