I don't have a CD player either. I rip my CDs with a DVD player - duh!

Well, a teacher robot that looks like Nancy Pelosi or Elizabeth Warren, would be the stuff of nightmares.

I know you think you're being super funny and snarky... but if you actually tariffed wildfires, I bet Canada would actually start doing things to prevent them

"Almost" = "not really". Forest management (clearing underbrush, firebreaks, etc) was a staple of human societies, going back to indigenous tribes. It's only the recent environmental movement that won't let humans into forests to do this simple task. And every time there's a wild fire, they blame global warming. And even sadder, most times it ends up being some environmentalist that set the fire in the first place. When humans don't manage the forest, nature manages the forest. And nature manages the forest by burning it down regularly.

Linus has been pragmatic about coding since he put Linux on a FTP server.

Yup, rather use Lexmark

Sure, and we are looking for thing that cannot. The photoelectric effect would be an example, unlike polarisation. But its still not a "quantum material" in the sense of the original article.

I'd be very careful about interpreting QM as "how it works". QM is a mathematical model that makes very accurate predictions for real-world observations.

... then piracy isn't stealing."

Ain't no way I'm letting some AI access to my passwords, no matter how "safe" they claim it is.

I guess a customer with Altzheimers may want to watch a movie twice, but he won't remember that he already bought it.

To be more accurate, it is neither a particle nor a wave, even though we may find it useful in certain circumstances to think of it as one or the other.
A quantum object is its own thing, a "quanton" . right? But what is real? The wave function? The measurement?

Everything is a product of QM, but to truly demonstrate it at the macro level, you need something like entanglement than can't be explained by classical physics. The polarisation demo is in the same category as the classical double-slit experiment - it proves that light is a wave, not simply particles. While the polarising filters are used in high-school to demonstrate Bell's inequality, they also have a perfectly valid classical explanation. The first filter replaces the original wave with its component in the filter direction. This new weaker wave has a component in the direction perpendicular to the original wave.

I'm not judging you for not understanding QM. Nobody does :-) But try to understand classical waves and vector components before you tackle QM.

No, it is a myth that a simple polarizer is a "room-temperature quantum material" in the way physicists mean it.

While polarization filters are fantastic for demonstrating quantum mechanics conceptually, the way a standard polarizer works can be fully explained by classical wave mechanics. It is entirely described by Maxwell's equations from the 19th century.

Haha yet, historically, it's the socialists and communists with an exclusive on forced labor camps.

And, it isn't.
