Well sure, at many orders of magnitude more cost. If you wanted to brute-force RSA, you'd be better off leveraging economies of scale to operate ten thousand current-gen 4nm GPUs running at 2 GHz with air coolers than a single exotic prototype 1nm ASIC running at 8 GHz with cryogenic cooling.

Aside from LCS35, most cryptographic problems are about as easy with two processors that are half as fast as one processor that costs twice as much.

That is if your problem is parallelizable. There are a ton of sequential problems that are hard or impossible to break up.

What would be an example that the NSA would be interested in?

Well I'm not an NSA engineer but I can imagine complex real-time analysis of streaming data, think processing 400+GbE link data. It quickly becomes too much too store, analysis could impose sequential packet dependencies.

> No, you can absolutely make specialized chips

proof? i'm just like... where? where do you think people are making these chips and using which ovens?

> smaller process size prototypes around

no there aren't. there just aren't. you could hide this in your basement about as easily as you could hide building your own space shuttle (and launching).

> no there aren't. there just aren't.

You do realize we all know it's impossible to have any degree of certainty in asserting the non-existence of something, right?

This is highly stupid argument, honestly. burden of proof lies on people that make idiot claims

Hume is deeply disappointed in you.

You can always turn a claim into a logically equivalent claim of the non-existence of any counterexamples.

    “For every instance, e equals mc²”

is logically equivalent to

    “There is no instance where e does not equal mc².”

That combined with your belief that claims of non-existence can't be held with any degree of certainty means you believe that no claim can ever be held with any degree of certainty. Which is not a very interesting insight.

This is an equally unsupportable claim, though. This requires enumeration of the entire state of the universe, an impossibility. This is just the standard swan problem (https://en.wikipedia.org/wiki/Black_swan_theory). What you have is a model you're very confident in without the deductively-rational basis your diction implies.

People should really read more hume if they're going to weigh in on philosophy of science.

> You do realize we all know it's impossible to have any degree of certainty in asserting the non-existence of something, right?

I love condescension that is so petty it's laughable. As the commenters said below there are very well-understood precedents/principles that allow me to conclude "no" here eg

https://en.m.wikipedia.org/wiki/Russell%27s_teapot

So no it's not "impossible to have any degree of certainty in asserting the non-existence of something", we actually have a whole branch of mathematics dedicated to exactly that (it's called probability and statistics).

Probablility and statistics are models that produce something we call certainty. This has no relation to actual certainty, aka knowledge. If you're making an abductive claim, you should state it as an abductive claim. Otherwise you're simply claiming true knowledge that is literally impossible to have.

Too late to edit, but probability and statistics do emphatically rely on past-certainty. The entire concept of using the past to predict the future, however, is just a convenience with no reasonable basis. Please appropriately hedge your comments as to not imply otherwise or be appropriately mocked in response.

This is precisely why I don't trust people who aver without receipts to show. Open the schools, goddammit!

Until I see some reasonable evidence that smaller process size cannot exist, i just see lazy people getting angry that someone disagrees with them. All of this "burden of proof" bullshit, aping like you're in some kind of formal debate rather than a conversation with a stranger, just screams "emotional asshole who can't deal with someone disagreeing with them and never learned how to engage in basic conflict resolution when they had the ability to engage in good faith and chose not to".

Y'all deserve all the mockery society can afford. I'm at least honest in that I see conflict is what we need more than ever if only to put people like you in your place.

> no there aren't. there just aren't.

There's no hiding anything here. You can find random articles about publicity stunts companies used to try based on these. Specifically when IBM was in the game, and Intel until they got butchered by incompetence.

where you get this nonsense? I am from semicon industry, so please, sources for the claim "orders of magnitude better"

Look at the history of 5nm process for example, from the first prototypes to mass production.
