The discussion centers on the idea of compiling information about historical personalities, with an initial focus on figures like Adam, Genghis Khan, and Cheng Ho. The aim is to cover 600 historical figures over a span of 6000 years, from Adam to Obama. However, some participants express confusion about the project's clarity and relevance, noting that similar information is readily available on Wikipedia, which may render the thread redundant. There are suggestions to narrow the topic to avoid overwhelming breadth, and the importance of sourcing information from academic journals and archaeological studies is emphasized. Additionally, the challenges of language barriers for contributors are acknowledged, highlighting the need for clearer communication. The conversation also touches on notable historical figures from various cultures, suggesting a diverse range of personalities to consider.
