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.
Was there a specific breakthrough you’re referring to with Li-ion batteries? Because they were discovered several decades prior to 2001. Maybe just getting manufacturing and mass production infrastructure up and running?
Well yes, goodenough invented them in 1991, but the density increases that tripled their capacities and themanufacturing capabilities that decreased their cost to manufacture by a factor of 10 didn’t happen until the mid-late 2000s.
There are also other battery technologies that you can release like glass batteries which are still being worked on today.
You could use modern tech to get a 30x increase in their ability per penny and corner of the market.
I think taking over the tech industry like this might be the most difficult strategy to take over the world. Firstly, the only way all of that info fits in a backpack is either if you commit it all to memory (which no single human has ever done), or you load it all onto a hard drive and keep it secret the whole time you’re in the past.
Second, if you do manage to keep it secret, you still need to know it well enough to leverage it to convince the Intel’s and AMDs of the world to fund you to create these advances in technology. A random homeless person who magically knows how to execute EUV lithography probably isn’t going to be given the time of day to prove it.
If you can’t keep it secret, and it leaks, you’re now useless and the Intel’s, AMDs, etc. with more resources will kick you to the curb and do everything themselves.
The lottery/investing strategy is probably the more lucrative strategy, depending on how much of a difference the butterfly effect makes.
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.
