I would say, if a person is able to write clearly and thoughtfully, and is competent at their role, they're very well suited for lots of jobs that aren't sales related. The meritocracy that gets touted so frequently (but is actually never upheld) should reward those that are competent at their advertised skills, right? If you're a really good programmer you should be able to find employment as a programmer, right?
Thanks for clarifying!
I can see how it'd be a major challenge to be deaf or bad at speaking at an in-person job where everyone else is speaking, though.
I'm much better at writing than speaking, myself, and find it much easier to convey complex ideas in writing (real-time or asynchronously). Especially writing vs. speaking through a conference app like Teams, where the latency can sometimes make things awkward.
