Has anyone come across this AI civilisation experiment? Curious what people think

So I was scrolling through X earlier and came across something that stopped me in my tracks. Some AI company has been running an experiment called "Emergence World" where they built five parallel worlds each powered by a different foundation model. 15 days, no scripts, no interference. From what I can tell the worlds started identically but diverged completely over time. One world ended in total extinction. Another got so conformist that agents started submitting absurd proposals just to test whether anyone would push back.
