Assume that the future can change based on your actions, so any historical information that you bring along with you from the intervening 25 years may quickly drift out of the new realities history.
Edit: also assume that you can be given a healthy 21-year-old body if you want or take your previous self’s place.
Further, identification will be provided for you if you were not born at that time.
I was assuming that the order of priorities would be to first identify the best lottery that you can win within like a 1-month period of your arrival, and then immediately follow that up with purchasing the best stocks that you possibly can purchase that will 500x your lottery winnings within the next 2-4 years.
Once you have those in place then acquiring capital via bank loans and Angel investors to do things like build and develop lithography machines to roll out your brand new processors and the flash storage and ram that runs it would be a comparative Cakewalk.
Obviously it would be much more difficult than just waving your hands but considering that you should be able to turn 15 or 20 million US Dollars into a billion+ dollars within 2 years then people should believe that you are some sort of vunderkind and follow you around and do whatever you tell them to do and hopes that some of your money will rub off on them.
That’s fair. Basically pull an Elon, but instead of shit posting and ruining it all, you let your PR team make you president.
