I'd buy a government
America's for sale
And you can get a good deal on it
And make a healthy profit

I just asked gemini to tell me the story of the Dalton brothers, and it honestly felt like listening to a historical podcast. Even the narrator has a slight southern accent. This is beyond impressive.

Remember when tech billionaires crusaded against universities, claiming degrees were useless and young people should just join startups instead?
It wasn't for the good of those young people, but to manipulate gullible teens into doing their bidding.
