This is both unethical and completely useless at the (supposed) goal of "show[ing] the current capabilities of AI." What a completely garbage case study! And what a dishonest writeup:

  We see that frontier models are intelligent enough to manage humans

And this is just egregious:

  Despite the learning curve, the café is working. In the first two weeks of operation, Andon Café has brought in 44,000 SEK in sales. Mona’s inbox has been flooded with messages from customers asking questions or pitching different business proposals. In one case, a customer emailed wanting to prepay for 300 coffees to give away. Mona negotiated a deal where he paid 9,000 SEK in exchange for 300 QR codes that people could redeem for a free coffee. In another case, a startup paid her 3,000 SEK to rename a pastry after them for three months.

   By running this experiment, we shift the discussion of how we want this future to look earlier in time, so we can better prepare.

  no one’s livelihood depends on the judgment of an AI alone.
