I say this as an autist who used to fucking loathe talking on the phone: Its that the phone takes up too much mental energy and time, yet has a time limit on your own responses. Its hellishly stressful when you are socially incompetent, and now a lot of even non-autistic people are becoming socially incompetent.

Now its funny, I hated phone calls back when everyone loved them. Now I’m pretty OK at them because I worked at a call center for a year and now it seems like everyone now hates phone calls. I kinda recognize that the one nice thing about phone calls is there is no “set up your account before ordering your food” type bullshit. There is a consistency.
