Earlier quoted context omitted.
> No I think they email each other. You never thought that some information needs to be received or conveyed in real time for efficiency? I only check my email once an hour, maybe every couple of hours. If people need to get a hold of me instantly, they call… like normal people. Even if I did check my mails more frequently, there's no guarantee that (A) I'm going to bother reading/responding to _every_ mail I receive…
Unless something is confidential, I don't use a phone. And luckily, I rarely need to be contacted instantly, as I don't like to be interrupted. I definitely never call my friends, we only speak to each other when we meet, and I read every email, but I never sign up for garbage emails. Although I would still want my phone to have excellent call quality. My best experience is with Facetime Audio.
But these sound like _personal_ preferences for _personal_ accounts.
In my work, and I'm sure most others, I don't have a great deal of choice of interaction methods, what I must be signed up to by email, etc.
Our own preferences are great and all, but I think that when we extrapolate those to the greater population and assume everybody is of the same mind, the blinkers to reality kick in. They're a huge problem that is endemic to the technologically-inclined because we falsely (and sometimes smugly) assume that our opinions and choices are universal.
Whether we might prefer or not prefer phone calls is irrelevant to whether or not people still do phone calls in the real world, and people have smartphones these days, so nobody should be surprised that smartphones are still used, especially in business, to place and receive phone calls.
Sure, mightn't be the top use case for a smartphone, but one would be foolish to imagine it isn't a big deal for a lot of people.
