Today's peeve: The "Smart Reply" function on my text messaging app.
This became active when I got a new phone and the default app for messaging was different. When a text is received, Google supplies some short replies I might want to send rather than write one from scratch. I've never used it, but I never bothered to turn it off. I have been the recipient of many of these messages from others. Often curt and vaguely or obviously inappropriate, I prefer to recognize the humanity of the other person by taking the 10 extra seconds to write my own words.
Today I got a group text from a friend with news of the death of a family member. It was a heartfelt and sad note.
Apparently, Google thought I might want to reply "That's great!," and as my klutzy thumb fumbled with the phone it hit that icon and that's the text I inadvertently sent to the group. One click, no "Send this?" confirmation, etc.
Lesson learned: I disabled the "Smart (?) Reply" "feature." It's gone now and I freed up some real estate on my screen.
