What Jamie wrote

This is one of the AI capabilities that I have been wanting to see for a while. I have found it incredible to engage with AI as a thinking partner on various topics. My GTD Coach experiment worked far better than I could have imagined. But I've wanted to go further. I've wanted to explore a topic not with one thought partner but with many.

TinyTroupe is an experimental Python library that allows the simulation of people with specific personalities, interests, and goals. These artificial agents - TinyPersons - can listen to us and one another, reply back, and go about their lives in simulated TinyWorld environments.

The packages documentation highlights a number of interesting use cases.

  • Advertisement: TinyTroupe can evaluate digital ads (e.g., Bing Ads) offline with a simulated audience before spending money on them!
  • Product and project management: TinyTroupe can read project or product proposalsand give feedback from the perspective of specific personas (e.g., physicians, lawyers, and knowledge workers in general).
  • Brainstorming: TinyTroupe can simulate focus groups and deliver great product feedback at a fraction of the cost!

Where do I want to take this?

I love the idea of a personal board of directors. I have some folks that I engage with this way. But how incredible would it be to design your specific group of agents to engage with and have each represent a different facet of your life, or an alternative vision of what you think success looks like. I could imagine starting a conversation on an important decision and seeing a rich dialog evaluating the question in hand from many different perspectives.

Solo projects could become much less solo. I publish the Weekly Thing entirely on my own. But if I could have a team of agents: marketer, editor, researcher, etc… And when I’m working on the Weekly Thing bring that "troupe" up to explore facets I simply never look at today.

This group dynamic or ability to create more complicated social simulations could be incredible.
