Around 2005 or so, Google floated (and let sink) the creepy idea that you should let them listen to your mic, so that they could supply useful info, for instance about the football game you were watching.
This is now the new normal. Pretty sure whatever is now weird will soon be normal too, given a spreadsheet or two to push it through.
(Heinlein was not nearly imaginative enough about the Crazy Years, no one could be. Might as well blame him for not thinking of the "Walk on Your Hands" thing.)
