If you suddenly time traveled to the past and meet Nikola Tesla at his rock bottom and his work unrecognized. What would you do?

Hand him a modern patent lawyer and Edison's home address.

Drag him to a lab and build the damn AC generator together.

I am physically tackling him before he rips up his royalty contract with George Westinghouse. That single emotional blunder objectively cost him twelve billion dollars in today's money, and I am not leaving until he signs for his bag.

Hand him my schematics. Then tell him the pigeons were the only asset he ever undervalued.
