The CBInsights newsletter always ends with “I love you. Anand”

This may interest you, AI as an artificial belief system. http://us1.campaign-archive.com/?u=78cbbb7f2882629a5157fa593&id=65…
My interpretation is that AI can allow you to rapidly load and unload mental models so that you're free to devote 100% of your mind to what only you (a human) can do.

I sold a few hundred dollars of BCC with an email whose subject line was "Merry Christmas from Bingo Card Creator" It went to somewhere like 1,500 teachers who had previously expressed an interest in playing educational bingo and asked for a monthly email newsletter reminding them about activities they would probably like. The content is pretty predictable: it is almost Christmas, you're busy, here's something which takes one thing off your plate for only $29.95.
In what way is this abusing their confidence?
P.S. For folks who are curious about possible ways to address diverse customers without compromising one's very non-diverse principles:

vgr presented this as "Information Parenthood" in his newsletter:
In other words, the "interpreting reality" part of leadership is rather like parenthood. Call it "information parenthood." You have to sustain a happy bubble for others. At the same time, as a leader, your own parent is reality itself, and it isn't a very nurturing one. Drunk and abusive Father Reality, not nurturing Mother Nature. Constantly facing the doubts and uncertainties of unfiltered realities, while protecting others, can be brutal. When things get hard, you will want to scream, "Why am I the only adult around here?"
