Young people text because it’s considered bad etiquette to call unannounced.

No such issue with robots.

That's definitely not the only reason. Again, I've known folks to have long, drawn out, back-and-forth conversations over text, certainly not just a "Hey, can I call you?" text intro, which is what I do.

Talking also bothers the people around you, and can tire you out if you do it for hours.
