Weirdly I really enjoyed MrBeast's line on this in his leaked internal production memo:
"Since we are on the topic of communication, written communication also does not constitute communication unless they confirm they read it."

This is why emoji responses on Slack are so useful. You can ask others to affirmatively confirm that they have read a message and they can make the confirmation without clogging up the channel with tons of text messages.
And no “read receipt” as it is usually implemented would not cut it, because it only means “this message showed up on the recipient’s screen once” not that they have actually read it.
