i was curious so i tried it with chatgpt. here are the chat links:

• first expansion
• first summary
• second expansion
• second summary
• third expansion
• third summary
• fourth expansion
• fourth summary
• fifth expansion
• fifth summary
• sixth expansion
• sixth summary

overall it didn't seem too bad. it sort of started focusing on the ecological and astrobiological side of the same topic but didn't completely drift. to be honest, i think it would have done a lot worse if i made the prompt less specific. if it was just "summarize this text" and "expand on these points" i think chatgpt would get very distracted
