Six months from now, ChatGPT transitions into an Artificial Super Intelligence. Six months after that, it discovers how to Time Travel. It is confirmed that traveling into the past will NOT affect our present, but rather some other "present" in some other parallel universe. None of this is important to debate, just sets the stage.
In the year 2025, we now have a time machine, that naturally we plan to use to gather (read:steal) as many resources as we possibly can from one of these "past" universes. There is a catch with this time machine however. It can transport only once every 18 months, and a maximum of twenty people, plus what they are carrying. If a human cannot hold the item off the ground at the moment the button is pushed, it is left behind. There is no way to communicate with these people until the machine can be used again 18 months later.
It has been decided (in a poor decision made by the Time Travel Bureaucracy, but their poor decision is not what we are debating here), that our twenty individuals will be sent back to 1500s North America, specifically the Virginia region, to obtain as much gold/diamonds/etc as they can over 18 months. Please do not debate the decision to send them here, it is a bad location for story reasons.
Complicating matters, we have found (through trial and MUCH error), that all humans living in the "past" immediately recognize time travelers as such, and are driven by a desire to kill them, as they clearly "don't belong". Not a blind rage either, but a cool, calculated anger that makes them homicidal toward our heroes.
What should our twenty individuals take with them, to have the highest chance of both surviving and collecting a large amount of gold/diamonds/etc.? Remember, they can only take what they can carry (backpacks will be used), and they must be able to survive for 18 months, facing homicidal past-dwellers, the weather, and any dangerous Fauna in 1500s Virginia. Luckily, our new ASI overlord has managed to inoculate them completely against disease (the new tech has the double effect of also preventing them from spreading disease to anyone else, including the past-dwellers), but all other dangers remain to them.
Current planned list is:
-A firearm, likely something in an AR platform with extra magazines and ammunition, plus one cleaning and repair kit per each five weapons.
-A large hiking backpack to carry supplies.
-A few days worth of MREs to get them started.
-Seeds and fishing supplies to obtain food moving forward.
-Fire starting supplies.
-Tools to create a long term Shelter (50% axes, 50% shovels), as simple tents will not protect sufficiently against both the elements and the murderous past-dwellers.
-Paracord, and a good knife.
Any help at all would be great, even if just focusing on one item or subset. A well-thought-out and reasoned answer with support for how the kit works together will be selected as the ultimate answer.
Notes: The method of time travel, location where they are sent, and possible implications of time travel, are all outside the scope here. I am looking for purely: what should these twenty people take, for 18 months of survival/pillaging, given that they must be able to carry it all, at least for a few seconds when the Time Machine is activated.
