It would be a substance of some kind that would have to be directly injected into the eye and would give viewers complete photographic memory that would enable them to remember and recall everything. It would have to be contained because of the dangers it can pose if used for military or criminal purposes. I just want to know what you think about how this might play out.
It's not a bad idea, but it would need to be well-executed, with the emphasis on the right points and no plot holes at all. It's sounding similar to SCP-868, but that goes in a completely different direction than what you're suggesting, so I dunno.
I think it would not be a complete memory, as in the fact that they wouldn't be able to remember audio stimula well, but they would be able to remember anything they focused on for a brief period. I want to make the substance like a bacteria that forms a symbiotic relation with the host to help enhance their memory.
The problem with this is that it becomes a magic item/dnd item due to usefulness. Really it's kind of funny how strongly we avoid this category of items, since if they existed they would most certainly get contained. But it is what it is - you write this concept the way you describe it and that's what you're going to be hearing people say.
You would really need to emphasize the negative aspects of this, why they want it contained so much, the measures taken to prevent its use becoming widespread. Without it this will be pretty uninteresting and fall fast.
There's really a sort of hilarious disconnect in general between things that make sense for the Foundation to contain and things that actually function well on the site.
Yep. Big alien monster with spike tipped tentacles that spears its prey and sucks out their innards? We could never contain that. We simply won't allow it to even exist in the universe for being lame.
A toaster that makes you think you're me? Holy crap contain me NOW.
A ring that lets you pass through walls? A sword that makes its wielder impervious to harm? A pen that writes the deepest secrets of the last person to touch it? A functional alchemy set that can change element types safely and stably? Nope, none of these can happen.
This is why I just assume that the chaos insurgency stole all the good and useful stuff and dangerous but controllable entities when they left, leaving the rest for the foundation to take care of. Otherwise the lack of useful items just seems suspicious.
I think the key to writing a useful item sucesfully is to think thru all the implications.
Take 668, that could easily be an artifact of legend in any DnD campaign. But it works as an SCP because the author considered the real world implications of an unbeatable weapon. Notably, human nature and the fact that absolute power corrupts absolutely.
Consider that phasing ring, it wouldn't work if it lets you walk thru walls. But it could work if you had to deal with the realistic consequences of passing solid objects thru each other, such as hard radiation, damage to atomic structures, and the chance of getting stuck part way. Or if the article had a good answer for the "comic book guy" questions:
How do you breathe when air molecules should be passing thru your lungs?
Why doesn't the wearer fall thru the floor?
How do you move without beign able to push against another solid object?
Hence why I specifically said "travel through walls" rather than "pass through matter" :P the ring manages to make the distinction that walls are the only thing you need to be able to go through. But yes, you're pointing out many of the additional reasons something like that would fail.
The human mind forgets things for a reason. It's one of our main coping mechanisms. Think of all those things you wish you could "un-see", and then imagine having them right at your mental fingertips, 24 hours a day, in HD like you wee seeing it again for the first time every time. There is room for some serious psychological trauma, especially considering what the Foundation staff might encounter on a day to day basis.
Also, if the recalled images are exactly as fresh and detailed as the real-time input, how can you tell the difference? I can see people getting lost in endless playback of memory loops, either to escape an unpleasant reality or because they just lost track of which ones are the present.
Eyeball injections are pretty squicky. But consider having it be contagious, like an anomalous strain of pink eye. To seriously depart from the base concept, I'm picturing how such an infection could spread itself. Infectees, their sanity no longer able to handle the constant barrage of impossibly detailed images, claw their own eyes out in an attempt to get some relief. This releases the spores into the air and propagates the species.
Hmm. There was an episode of the British suspense show "Black Mirror" that dealt with exactly this subject ("The Entire History of You"). In that episode pretty much the entirety of humanity injected itself with a chip that allowed them to review memories as much as they pleased, and the consequences of being lost in memory or in obsession about it. Well worth a watch.
