A computer with lists of winning lottery numbers, stock prices by day of all major companies, archived copies of webpages or, preferably, scanned in newspaper articles of all world events from 1999 until now, and lists of every politician and individual with net worths over $300 million.
Also patents for LCD screens, the microchips in use in the 10’s and now, the efficient solar panels China cranks out if I can get a hold of that information, modern efficient wind turbines, etc. Also important scientific papers written between then and now, especially for Ozempic and Wegovy.
Also, this might be the one practical use for dumb shit like Chat GPT and its ilk, so we’re bringing along a couple of GPUs and copies of each major open source AI I can scramble up.
I use this information to:
Hopefully prevent 9/11
Become filthy fucking rich
Infiltrate the elite and start bumping off motherfuckers one by one Count of Monte Cristo style
Distribute my ill gotten gains to the masses and use the rest to stop climate collapse
