Apple Airpods will read out incoming messages to you - whatsapps, slack. I like it. I like the way every message is flattened into the same tone and voice. It's like the Radio 4 news reporting on the activities of your colleagues.
It also lets you shake or nod your head to accept or reject messages or interrupt and silence a long one. I like that too. You have to shake quite vigorously. It makes popping and ringing sounds as you shake so you feel a bit like a jester.
I realised, the other day, how habituated I've become to that.
Someone was talking to me in a shop, too much, and my body was trying to get me to shake to decline. Fortunately my conscious mind intervened and I avoided looking like a rude fool.
