I’ve got no motivation to take over the world, nor am I sure it’s really possible in a life time. I don’t really have a non-boring answer to this hypothetical.
If the ticket is available anyway I’d happily take it, I’m single at the moment with no dependents and being younger and healthier would be huge. There are lots of ways to make money with the knowledge of future history, even if it’ll change when you start impacting it, and any one of them could make me wealthy enough to never have to work again in my life and do so wherever I please.
I’ve never really understood the need of the rich to continually amass wealth or how they spend it.
