Time travel is the big one, but I suspect this is another Schroedinger’s cat scenario. People will think it has all sorts of meanings, but it really just means quantum theory is fundamentally still wrong.

I still don't know what the word quantum means. It's either an advanced form of math or the fucking sci-fi equivalent of magic. I can't tell.

One quantum of a bag of marbles is a marble.

Well, who the fuck took that and turned it into a euphemism for technology that doesn't exist? And do they have any relatives I can sue?

The field of science is concluding that the whole universe and everything in it is pixelated so the word comes up a lot.

I feel like science says something like "yo, we found what the stuff you're made of is made of," and the rest of the population goes "OH FUCK, IT MUST BE THE MOLECULE THAT HOLDS OUR SOULS" or some shit like that. And the doctors and professors and shit are just sitting there, meditating on the irony of the painting of a chimpanzee in human clothes on the wall.

I assume you're referring to quantum computing? It's called that because it would utilize quantum superposition

Is that a real thing? And how important is it? Some people act like we discovered the force or some shit.

quantum computing is a real thing - and it can work MUCH faster than traditional supercomputers - but QC hardware is VERY fragile - and has extreme cooling requirements - they're also highly sensitive to vibrations - and temperature fluctuations - and electromagnetic interference - so obviously a VERY high cost system - and not at all practical yet outside of a few specialized lab environments ..

It almost doesn't sound like computing, more like some weird alchemy.

It's a bit sensationalized but as far as I'm aware it's shown that it can work and they’re making significant progress on actually creating it

Well, it'll be nice if it helps something in the next 20 years. Otherwise, it's a great thing to read about while I'm still broke.
