Edit: Why is this perceived as infallible?

I don't agree with these arguments.

> An organism has the basic instinct and right of self preservation.

If you want to ensure self preservation, take steps to create an environment where the likelihood of survival is higher not lower. All the reliable evidence that I've seen points to higher gun ownership correlating strongly with higher murder and suicide rates and to the USA being an outlier in terms of violent crime as compared to other developed countries.

> Police generally focus catching criminals after they've committed a crime.

Well where that's true (and having lived in several countries, its not true everywhere) that's certainly a failing in law enforcement.

> a gun equalizes your chances with potential attackers.

This is extremely doubtful. Attackers generally attack in groups. They typically have planned their attack whilst you're taken by surprise. Also criminals are generally better versed in violence than the typical citizen. Pulling out your gun is often likely to turn a robbery into robbery and murder.

> The ability of the population to make things difficult for the government to institute total martial law is a basic check on wholesale removal of civil rights or due process.

This is the most ludicrous of all the gun lobby arguments. Seriously, you're planning on subverting the US government with your collection of handguns? The same government that spends more than 500 Billion on military expenditure/year?

> People seem to think militias in the mountains of Kentucky would be completely ineffectual in this regard but fail to notice how the Taliban has been very effective for decades in Afghanistan.

Afghanistan is a failed state. The Taliban are likely funded by a lot of well heeled supporters included their partners in the Heroine trade.

I'm honestly still baffled by how the concept of "freedom" got conflated with gun ownership in the US.

Personally I prefer the freedom of not having to be worried about being shot by any disgruntled imbecile who takes advantage of his "right" to a gun.

I would really appreciate an explanation of this. Right now it seams like just a fantastic marketing/brainwashing strategy by the NRA but I would love to hear a well explained argument for this.

Well there are people on here that are saying literally: - cryptocurrencies should be banned - government regulation is the solution (with the implication that government is extremely concerned about the well-being of the populace in general, and investors/speculators specifically) - the people investing don't know what they are doing and need to be protected from potential losses

If there's something I've left out from this particular argument please let me know.

> The question is whether that is in any way related to the current price of BTC.

Of course it is. People paying money on foreign exchanges contribute to the price too. Foreign remittances are a fantastic use case for crypto (mostly to these same countries).

Also, what inspires many people to enter crypto, is general lack of trust in government and financial institutions. People choose to buy crypto rather than buying other asset classes or to hold fiat (this is a decision with a strong geopolitical basis).

> It seems like the large majority of trading is happening among people who live in other nations and who already have wealth.

Possibly, but thats besides the point. This argument is a refutation to several arguments that detractors make: - there's no use case for crypto - there's no underlying value to crypto - crypto can't replace a fiat currency

> This isn't a technology that protects the developing world against monied interests. Its a technology that amplifies inequality due to an enormous difference in cost depending on when you joined the network.

As the Big Lebowski said "that's just like, your opinion man".

Joking aside, there are good reasons to think that crypto could in fact allow many people who are currently stuck outside the financial system to have access. This may me a small use case right now but its still early days for the technology.

I'd encourage you to watch: A. M Antonopoulos 'What Bitcoin Means For Unbanked Economies https://youtu.be/xeSfDbbcN2c

The article I linked to was from ABC news (as mainstream a news source as you could find).

How is this propaganda? You're saying people in countries with hyperinflated currency have no use for crypto and don't use it? Can you back this up? Can you explain why there are significant premiums for Bitcoin when buying from exchanges from these countries? Or is this propaganda too?

Of course there isn't data (except of course from the exchange rates). These people are breaking the law and at risk of death or imprisonment. What type of evidence would satisfy you?

Commodity: noun, plural commodities. 1.an article of trade or commerce, especially a product as distinguished from a service. 2.something of use, advantage, or value. 3.Stock Exchange. any unprocessed or partially processed good, as grain, fruits, and vegetables, or precious metals. 4.Obsolete. a quantity of goods.

So if you're saying its a commodity (and therefore should be taxed), it has value (and has to be based on something).

But semantics aside, taxation is theft, even more so in this case - there's no justifiable reason to hand over a portion of the gains to a government that had no involvement in the creation of the source of revenue.

neuro_imager··on South Korea considers cryptocurrency tax
Its probably impossible to quantify (mostly because those people using crypto are largely doing it at risk of imprisonment or death) - I'd imagine its a small number of tech savvy individuals.

> It's a fair concern that something so volatile should be examined critically and relentlessly.

I agree - but backed with concerns based on legitimate understanding not "price is going up quickly, must be a scam".

> I think governments/regulators should have some say the same way you'd want them to regulate any financial instrument and punish Ponzi schemers and pump-and-dumpers.

Because they did such a great job in 2008? When are they planning to punish the architects of the financial crisis? Who's going after the banks when they launder money for mexican cartels and ISIS? You really think these people are trying to protect the public?

> I'd like to think about the motives of both sides from being so passionate.

I can't speak for anyone else but I come to these threads hoping to find sensible insight and technical analysis not "THIS IS A BUBBLE! BAN IT!"

> For yaysayers, it's a bit more obvious---once the hype dies, they'll stop making money.

There may well be a huge correction but the overall market is anti-fragile and here to stay.

Well, for one, drawing conclusions about the market circa market cap of 15B is very different to assessing it now at 275B.

This thread reminds me that even on HN most comments on the internet are from people with very little understanding. I expected the "bubble", "tulip", "no value" arguments to come from the chicken littles on Forbes.

If you think Bitcoin is overvalued, fine. Pour yourself a stiff drink and accept some people might lose some money.

The sort of emotional hyperbole on here about "cryptocurrencies need to be banned by the loving, paternal, incorruptible government to save the world from ourselves" is not just getting old, its absurd.

Having a censorship-resistant, globally-accepted asset would grant an unparalleled financial opportunity. Even if Bitcoin falls short in practice – it’s closer to the mark than any non-crypto asset.

Being able to send money around the world with real-time market-based fees that are often lower than many alternatives is useful. Having a place to park value when banking is not available is also useful. The list goes on…

Do you trust the government and the financial institutions that much that you're willing to hand them back the reigns of your financial future?

I admire the certainty of the naysayers on this thread. I only wish I could borrow their crystal ball.
neuro_imager··on South Korea considers cryptocurrency tax
Yes, because governments and their financial sector cronies have a history of brilliant financial decisions that benefit their citizens.
neuro_imager··on South Korea considers cryptocurrency tax
What is the crime here exactly? Breaking up the financial cartels? Regardless, I have no doubt that the government will do their best to use this as yet another opportunity to steal wealth from their citizens.

The people in Venezuela and Zimbabwe that are now using crypto as an opportunity not to starve now that their fiat currency is worth less than toilet paper disagree.

edit: Rather than downvote - could you please explain why you think crypto is not beneficial to the billions of people worldwide currently excluded from the financial system?

neuro_imager··on South Korea considers cryptocurrency tax
You know you're citing articles that are almost a year old?

Please also provide evidence that "all of the early buyers are selling".

Its ironic that the same people who keep saying cryptocurrency has no underlying value, that its just a speculative bubble, are saying that profits from its increase in price should be aggressively taxed.

Its ironic that I've chosen not to buy his new book on VR yet, because its only available in hard and softcover, not audible.

That being said Leron's work is phenomenal and I'd recommend "who owns the future" to everyone.

neuro_imager··on What happens when patients find out how good their doctors are? (2004)
The first part of your comment is a great question.

Its extremely hard to definitively define best practises. You'd be surprised how many practitioners still argue for what look like clearly outdated ways of doing things. There's also the argument that in some people's hands an outdated way of doing things is safer than a newer (better?) way of doing things in their hands. eg. A surgeon who has been practising for 30 years but only recently learned to use a laparoscope.

I doubt ambulance chasers do anything other than muddy the waters and enrich themselves at the healthcare systems expense.

Honestly, the only way I can think of would be for the system to be rebuilt from the ground up with more objective, reliable, verifiable data (and data capturing mechanisms).

Accumulation of power inevitably leads to abuses of said power, at least in my experience.

As someone working in one of "America's best hospitals" I can confirm that those consumer reports are a complete joke.

Overall, I like the idea of a metric such as the one you describe. However, a change in one year mortality rate is unlikely to be a reliable indicator of the efficiency of most treatments. Most medical interventions have more modest effects than definite improvement in short term survival.

There's no easy answer for back/neck pain.

I will tell you that yoga/pilates/other non-ballistic, moderate resistance exercise that targets stabiliser muscles helps many people.

I would avoid surgery at all costs unless you have cord compression, a focal lesion or a fracture.

I'd be very wary of chiropractors - I've seen several patients with vertebral artery dissections (with incapacitating brain stem strokes!) because of neck manipulation. Of course, I have a selection bias but even a small risk for this seams like too much.

neuro_imager··on What happens when patients find out how good their doctors are? (2004)
Yes people have come up with these metrics (mostly bureaucrats with a fetish for anything that looks like data).

As far as I know no-one has come up with a metric that's actually useful for students and teachers.

Few initiatives are as bad as they sound as PROMS (patient reported outcomes). Very good for people who like power lunches, excel spreadsheets and having numbers to vocalize - worse than useless for patients and physicians.

Sure, optimising environmental factors would undoubtably be helpful and is a laudable goal.
neuro_imager··on What happens when patients find out how good their doctors are? (2004)
Actually what would be naive would be to think that you would be able to change the situation by whistleblowing.

And before you judge anyone too harshly, talk to me again when you have 300k of debt and you're a fourth year resident stuck in a singularly focused career pathway.

Also, the reality is most people have so much else going on to concern themselves with that these things are given little thought.

> Give participants (patients, doctors) access to subscribe to health data or symptoms (input) and create a consensus of possible treatment plans, iterate through those plans ordered by some metric (reputation, time, cost, availability).

I'm still not sure I understand what you mean. Could you give an example?

> When cure confirmed by patient, diagnosis is proven correct, data is captured, reputation increased among participants in consensus that were correct.

It's not that simple. Most patients are not either 'cured' or 'not cured'. There are multiple possible outcomes at each stage of diagnosis and management.

> You could even use this as human-in-the-loop machine learning model training for open models.

Doubtful. Current machine learning algorithms are painfully inept when given clinical data (outside of very limited use cases). I'd love to be proven wrong though.

In fairness, misdiagnosis of appendicitis is largely down to utilisation of technology. Most modern institutions utilise imaging (ultrasound/CT) and this results in a high specificity for appendicitis (especially CT, which doesn't suffer from the user variability that ultrasound does).

Old school surgeons will insist that they can reliably make the diagnosis without imaging (and that's probably where you get a 20% false positive from). Some institutions will push this notion too - either to reduce imaging expenditure or increase surgical turnover (sad but true).

> We don't really need truely objective assessments. As an analogy, imagine we randomly added or subtracted 3 minutes to the finishing times of all the runners in the Boston marathon. We wouldn't have a truely objective assessment of each runner, but it's still a useful guide about who is likely to beat whom in the next marathon.

I don't think the analogy fits. There's no single metric (like runner speed/time) to evaluate competence.

> This problem can be alleviated to a large degree by risk-adjusting the outcomes: For each patient, estimate the most likely outcome and compare the actual outcome to the estimate.

Agree.

> I don't see this as an insurmountable obstacle. For example, you could have an independent body randomly sample the reported outcomes to check that they are accurate, and apply some kind of penalty if they are not.

That would be a good solution. Part of the problem is finding a truely independent body. Medicine is over-run with various governance and regulatory bodies (several of which have been shown to be little more than rent collectors). And again, there's the problem of deference to eminence combined with small in-bred communities within each speciality or sub-specialty (who would likely be the only people with the training to evaluate their peers reliably).
