@glyph Did you quote post something?

@miss_rodent the expert I would go to ask about that is @xgranade and I am pretty confident that she would not be bullish on this particular likelihood any time soon
@glyph Fair, was just a suggestion for a potential 'next thing' that might actually work, though last I looked into it (admittedly been a few years) it did... not seem particularly hopeful as a 'next big thing', at least not anytime soon.
As far as I know it still has quite a few limitations and caveats to what it's useful for, and of course the major limitation of all computers, being restricted to, y'know, only things which can be computed or achieved by computation in the first place. -

It's definitely not The Way Computers Will Work and the things that it will unlock seem like pretty quiet infrastructural improvements and not significant population-wide stuff. Per my existing thesis I do think it's almost certain that it will, at some point, be A Thing, but it will not be Big

@glyph @miss_rodent Yeah, no, I'm not particularly bullish. There's a couple parts to why not... while I'm quite convinced that building a quantum computer is probably possible, and we have some good mathematical evidence to back that up, it's been five years away since 1997. I'm suspicious of any particular claimed timelines, as the problems left to be solved are huge.
The other part, will quantum computers create a new class of easy next big things once built, that's more complex still.

@glyph I've aspired to "lunch-scale projects" for several years now. Intentionally meaningless—semantic choice in opposition to the differently meaningless "Web scale"—but generally:
- not for crowds (used by one person at a time, maybe a small group)
- bite-sized projects with a smaller scope
- the kind of work where I could fix the average bug before lunchtime
These ideals *have* made it hard to be persuasive in dev job interviews, alas.
All this to say I agree with the thoughts and CTA.

@glyph @miss_rodent The short version there is that we currently haven't found any *practical* problems for which quantum computers are *provably* better than classical computers by a large enough margin to justify using a quantum computer.
We've found impractical problems (she said handwavingly af), and practical problems like cryptanalysis where we have good evidence that quantum computers are better, but no hard proof.

@glyph @miss_rodent Part of that is that it's hard to come up with new algorithms when you don't have the hardware to run and test them on, leading to a chicken and egg kind of situation. Part of it, though, is that what quantum algorithms — not programming quantum computers, but coming up with genuinely new algorithms for them — tend to require a peculiar kind of cleverness and trickery that slows down the search for new problems which might admit a quantum advantage.

@glyph I am very, very tired of Next Big Things anyway.
-
@miss_rodent @glyph I'd even go beyond theoretically possible, as someone who did a lot of quantum computing work. I think the set of things that would have to be true for quantum computers to be fundamentally impossible or even inherently impractical would be pretty surprising.
At the same time, I don't have any particular evidence that we're especially close, nor that there's any easy wins in terms of Next Big Things once one is built.

@miss_rodent @glyph Chemistry is about as close as we have to a field where quantum computers are probably going to be commercially useful, which could unlock some several dozen new exciting materials science things, but that's pretty far from (as to @glyph's point) what VCs seem to expect, where every company will need to buy up QC time. It might even be a bigger impact in the long run, but it sure as hell isn't VC's Next Big Thing.

@miss_rodent @glyph (Sorry... I tend to infodump on demand about quantum computing.)

@miss_rodent @glyph (Sorry... I tend to infodump on demand about quantum computing.)
@xgranade @glyph I tend to infodump too, so, very much no need to apologize/I appreciate the input, it's a field I have looked into a little bit but not very deeply or very recently, just kinda looked into it as something tangential to the residual math/physicist nerdery that lingered after I dropped out of Uni.
And yeah, it seems unlikely to be a thing corporate and finance types would be that interested in, or if it will be does not seem like it will be anytime soon.

@miss_rodent @glyph (Sorry... I tend to infodump on demand about quantum computing.)
@miss_rodent @glyph I guess the last thing I should add is that there's a lot of problems where we know a priori that there *isn't* a quantum advantage — if someone spends most of their CPU time now on one of those problems, then they're not likely to be a huge QC customer, making it harder for VCs to sell quantum computing as the Next Big Thing.

@miss_rodent @glyph I mean, there have been at least two or three big waves where corporate and finance types were very *very* interested in quantum computing. I think, and again to @glyph's point, there's a large degree to which that can be explained by zero or negative interest rates.
Each time, there's a concrete event that sets off the hype wave, and it dies down when people realize that QC is *always* five years away.

@bitprophet you're the first one to catch that (I guarantee it hurt more to write than it does to read :))
@glyph the rest of the post is good too btw!

@miss_rodent @glyph Like, one time wound up being a coincidence between the timing of a complicated bit of tax... er... well, not *fraud* exactly, as it was all perfectly legal, so I'll call it tax shenanigans... around the F-35 project and the Volkwagen emissions fraud that indirectly created a gigantic hype wave. That was weird.
Another time, it was the failure of an NLP-based "AI" product that created a hype wave.

@miss_rodent @glyph I'm being intentionally vague here in public, but I promise those are both fully accurate descriptions even if a bit cryptic.

-
@miss_rodent @glyph Yeah, no, fair. It's a weird one in that I think there's a lot more there there to QC than AI, by a long shot, but also it's not the line-go-up kind of thing VCs seem to hope it will be, and definitely not on the timescales they seem to think that it will happen on.

@ireneista @cthos @xgranade this isn't exactly a "cheerful" thought, but it's also not horribly grim: I think we already saw it break down in 2020, and we saw both how brittle it is (nobody had enough slack in their supply chain to actually weather the disruption without exposing catastrophic delays to customers) but also its resilience (customers were super mad, alternate pathways DID come online in less than a year)
