I can't say I have any experience with PVS-14 or any Night Optical Devices, but from what I see online, it amplifies certain visible spectrum as well as near-IR. It doesn't seem to rely on IR much. And red dot sights aren't even IR are they? At least not entirely, cause you can see them with the naked eye.
Regarding glass being opaque to IR, apparently, it depends on the type of glass. I just remembered it from a Vsauce video (IIRC) where it was demonstrated to be opaque. But since term IR is vague and doesn't have super defined borders, and there are different types of glass, yeah, it's not a certain statement.

Fair enough, I was being too vague with my statement. I was implying that they don't emit much IR, as all bodies above 0 Kelvin do emit it. And LED/laser headlights almost don't, in comparison to xenon and stuff. I looked up some Xe emission graphs and some even straight up show the peak in near-IR, while laser/LED starts flatting out way before NIR.

Well, IR isn't heat, but it's associated with it. And since laser and LED lights heat up a little bit, yes, they of course produce a miniscule amount of IR. But it's pretty much negligible in comparison to their visible spectrum emissions. If you're already being blinded by the visible range of the laser, the IR part isn't gonna do much.

Yeah, it's absolutely clear that nothing is clear about its operation.

If I understood correctly, it captures visible light to use it for the amplification of the IR spectrum.

Now that I've read my own comment, I see that it came off harsher then I intended it to. Interpret it literally and not like a sarcastic statement.

Btw, just occurred to me that these would probably not work in a car at all, because regular glass is usually opaque to IR.

Do modern headlights emit IR? I don't think so. Which means these IR amplifiers wouldn't change the intensity of headlights.

I'm not sure about iPhones, but iPads have had homescreen widgets for a whole year, maybe even two!

That's ok an all, but I assumed that you do care about making a false statement, which was the point of my response, to let you know.

You are being downvoted because you're factually wrong. While Android (especially on Samsung devices) had been getting more locked down over the years, even unrooted it has way more freedom than an iPhone. For instance, you can install any number of APKs, without jumping through any hoops.

You took my comment too seriously, it was just a joke.
But you also singled out Intel. Corporations aren't heroes in general and AMD is also there. And EU is depicted as the villain, although it's implied it's the hero in the context of the meme.

I would argue that the meme has long lost that particular aspect of itself and the character alignment is ignored. In this instance, clearly indicated by Surtr being EU, while the context heavily implies that EU is the "hero".
