Atheist utilitarian technology professional here. I read tarot. Not because I believe anything mystical is coming through the cards. They just happen to be a very rich and rounded set of symbology to lay out and use to talk through a topic. I have never had anyone walk away from one of my readings without saying “that was more interesting than I thought it was going to be.” Of course my style is very interactive and I involve them a lot as we go. Of course others out there take an oracular approach that’s utter horseshit.

No, tarot is a fantastic card game : https://en.m.wikipedia.org/w/index.php?title=Tarot_card_games&diffonly=true

Cartomancy using a tarot game cards is stupid though.
