I can picture a future where people don't bother with that. Similar to how we slowly abandoned landlines to go 100% mobile, I can imagine people going to data-only plans.
I'm about to get a phone for my kid starting high school next year, and frankly, I can see already see a case for just getting him a data plan.
Not exactly (I don't think). You could choose pre-written responses, but only after the initial spiel about the screening and eventually you'd have to either hang up or answer the call. This is more like you can just pick up the call and text whatever.
If you think you hate 2 minute long voice records in text chat, get ready for 2 minute long texting on voice calls. I understand this is more for accessibility to people with speech impairments but at that point why call instead of texting anyways?
