A while back I gave it a prompt, something like, "I'm a historian from the far future. Please give me a documentary-style summary of the important political and cultural events of the decade of the 1980s."
It did ok, then I kept asking for "Now, the 1990s?" and kept going into future decades. "Now, the 2050s?" It made some fun extrapolations.
