I imagine the data won't be very useful considering it's public knowledge the store is run by AI and most of the customers will be people specifically interested in that aspect of the business. Much like that meetup organised in Manchester, where the people who showed up were there for the novelty: https://www.theguardian.com/technology/2026/apr/05/ai-bot-pa...
That only counts if the unique selling proposition is that AI are better suppliers or customers than humans.
What is more likely is that people enjoy the novelty of the experiment, which is not something that will be reproducible for long.
If the transactions the AI make are thus influenced, then the study merely demonstrates people like novelty, which is already well known, and says nothing about whether AI can sustainably orchestrate a business.
