The last one is fairly simple to solve. Set up a microphone in any busy location where conversations are occurring. In an agentic loop, send random snippets of audio recordings for transcriptions to be converted to text. Randomly send that to an llm, appending to a conversational context. Then, also hook up a chat interface to discuss topics with the output from the llm. The random background noise and the context output in response serves as a confounding internal dialog to the conversation it is having with the user via the chat interface. It will affect the outputs in response to the user.

If it interrupts the user chain of thought with random questions about what it is hearing in the background, etc. If given tools for web search or generating an image, it might do unprompted things. Of course, this is a trick, but you could argue that any sensory input living sentient beings are also the same sort of trick, I think.

I think the conversation will derail pretty quickly, but it would be interesting to see how uncontrolled input had an impact on the chat.
