As in, you have what is considered “alien” technology that’s 100,000 years newer than anything invented or available today. By then, most humans around today are deceased before that’s even invented due to it being beyond our own lifetime. First, it would be studied if anything of that sort is available now or an equivalent but nothing comes close. People may ask questions as to how you acquired such advanced tech.
Governments may force you to mass produce that against your will if the demand is high, but again comes with its own issues: the materials it’s produced from are beyond what we already acknowledge (not yet known until later) but, they may just coerce you to extract such materials and resources. The futuristic technology will look nothing that’s depicted in science fiction, since it’s something we don’t even understand yet.
It’d just be a silvery stone. That you’re supposed to operate technopathically. Because all humans get a technopathic link when they are gestated.
Or it’s a sword made of bronze. Because we’re in the Bronze Ages v7 and the dominant species is humanoid bears.
Or there’s nothing because a sieve bomb perfectly deleted any manmade product from the planet, reseting it to a primordial state.
We can’t even pretend to guess technology from even 1000 years in the future, let alone 100,000 years. This is just a creative writing prompt with basically no constraints or rules.
100% but we should also consider ‘my’ (I certainly do not own it in any way) take on the prompt as another valid way to (try to) answer the OP question.
More than likely, we will not even realize we got handed over some tech wonder gizmo thingy… which we will agree doesn’t make for a great story. So, we would need either … to not be who we are (which kinda invalidates the question), or to be offered a much less advanced tech, something we could realize is worth something. Suffice to observe how UFO theories have always been flirting with our very own most advanced tech, barely a couple steps in front of it (some more joyfully wandering around than others, too), while discarding their previous ‘advanced’ tech/theories the moment our own reached a similar level. Something that, btw, makes for a perfect business model as one can easily write the same book/documentary, over and over again just changing a few words/gizmo/witnesses here and there. Not saying that’s what our UFO experts are doing, obviously not.
That being said, I quite like your humanoids bears with their bronze swords :)
