It's not that WWW was quick, it's that Bitcoin is useless.

False, it was much more annoying to buy drugs online pre-crypto.

How did people do that before crypto?

Money in mailed in envelopes. Western Union. Prepaid credit cards. Stolen credit cards. Bank transfer to a legitimate business that funnels it to their drug empire.

For agent to agent payments, Bitcoin/Ethereum could be quite useful now, as traditional payment protocols and banks are not likely to provide decent APIs any time soon.

I've also heard Cory Doctorow recently offer a similarly dismissive view, describing AI as "just statistics".

> I've also heard Cory Doctorow recently offer a similarly dismissive view, describing AI as "just statistics".

Well, AI partisans have applied grandiose terms like "thinking," "intelligence," and "soul" to these machines. It's not wrong to push back and remind people what they really are.


Well, if you look into the current scientific consensus on human cognition, our intelligence is also "just statistics."

So I guess we all agree, except that some people think "just statistics" is derogatory phrasing!


What a software engineer comment.

That is absolutely not the consensus in neuroscience.

Was thinking more about cognition than neuroscience, but sure, even there. Think of any counter-examples -- I'm guessing things like symbolic reasoning or pre-existing structures in the brain -- and then consider the origins of those concepts.

Admittedly I'm an absolute layman just dabbling in this, but I could find not a single concept that cannot be traced to statistical origins. Like, symbols are essentially "vectors" of thousands of neurons firing simultaneously, and the pre-existing structures in the nervous system originate from evolution, which is a statistical process.

"Just statistics", as far as I can tell! ;-)


Over the last few months, I’ve increasingly come to believe that depression is not caused by a chemical imbalance. After trying ten different antidepressants with no success, I found far greater improvement by changing my patterns of thinking.


Adding one letter to the day of the week would be way less confusing.


No need to look too closely, now ;)


I think they mean writing Tu Th Sa Su instead of T T S S (personally I'm a fan of T / theta if I'm doing single-letter abbreviations but Sat/Sun is still not the best)


Thorn, Þ, seems a more natural choice. The rune is called thurs, even.

I guess there's katakana Sa サ and Su ス, if that's an improvement.


yeah, but I was a math major and theta looks like a normal letter to me whereas thorn takes me a sec to realize what I'm looking at

I like the katakana idea, I wonder if I can train myself to recognize the Su one enough to start using that when I'm handwriting days of the week places


Maybe we should all adopt Chinese weekday names: Sunday (星期日) remains same, Firstday (星期一) for Monday, Seconday (星期二) for Tuesday, Thirday (星期三) for Wednesday, Fourthday (星期四) for Thursday, Fifthday (星期五) for Friday and Sixthday (星期六) for Saturday. One-letter abbreviations would be simply S, 1 through 6.


I believe that's how Russian names the days as well. In Hebrew and Arabic we do the same, but Sunday is First Day, Monday is Second Day, etc.


Not all of them, though:

Monday - "понедельник", which is coming from the "day after the (previous) week", i.e. after the Sunday Tuesday - "вторник", true here, has "second" in the name Wednesday - "среда", has "middle" in the name Thursday - "четверг", also true, has "fourth" in the name Friday - "пятница", also true, has "fifth" in the name Saturday - "суббота", derived from the Hebrew "shabbat" Sunday - "воскресенье", almost the same word as "воскресение", which is the Christian Church word for the Resurrection (of Jesus Christ)


Why downvoted? This is correct.


He was a con artist with a Nobel Prize.

It's interesting having this video be my introduction to Feynman, then seeing how people talk about his personality.

She brings up points that don't seem easy to dispute, yet all of the comments here seem to be praise for the man outside of just his achievements.


This website is 99% the sort of not especially socialised young men who for various psychological insecurities are prone to the sort of hero-worship that she refers to in the video.


Every person is a con artist if you’re cynical enough.


As I wrote in a comment about the same person, be careful, she is a far-leftist that regularly pushes a "particular" agenda in her entertaining videos about physics and life as a phd student.


A "con artist" does not invent the action formulation of quantum field theory.



When I tried to install the Windows release, I got a message that it contains the Vigram.A virus.


I got the same thing and worked around it by installing the previous release.


See https://github.com/qutebrowser/qutebrowser/issues/8389 - unfortunately there's a lot of stupid false-positives especially with PyInstaller (packaging a Python application into an .exe). Happens a few times a year, unfortunately there isn't much I can do other than submitting a report to Microsoft and hoping they'll react ¯\_(ツ)_/¯


It's buggy. I got stuck in the blue "pool" in the last stage, under one of the green ramps.


My impostor syndrome is cured a little when a machine learning expert mentions acupuncture.


I dunno, my normal doc referred me to some clinic some time that did some kind of accupuncture. I’m not given to the interpretation that he believes in alternative medicine, so there must be something to it.

I thought people sticking needles in me was fucking scary though, so I never went more than the one time.


i dunno man, i was in pain for 2 full years, people try alternative medicine when when main stream medicine does not work, whats a couple 100$ dollar difference does it make?


The core of most alternative medicine is: listening to your body, easy exercise, and taking time. In other words, the perfect circumstances for your body to naturally recover.

But then the patient and practitioner attribute the recovery to needles, or energy beams, or homeopathy, or religion.

Well, I'm happy that they recover.


People have always loved gambling. Crypto is nothing but a game of musical chairs. Also, smart people fall into cults like everyone else but they tell themselves they are into it for rational reasons (techology).


Do you have any criticism to offer as to why BTC isn’t viable?

I’d love to be convinced. If I hear a single convincing argument I’ll beat that drum all day alongside you.

But all you’ve given is:

- gambling exists

- “musical chairs”

- cults exist

So, hand-waving. Help me out here.


It has no underlying fundamentals. Its value is 100% speculative. Gold is somewhat similar, in that it's value is mostly speculative, but it does have some inherent utility/value.

Bitcoin has value for the same reason that vintage sneakers or Pokemon cards have value; that is there is a fetish for them and thus some belief that at some later time, someone will want to buy it for personal reasons (either due to their own beliefs or sentimentality).

Actual currency, on the other hand, derives its value from the willingness of the issuing sovereign to accept it back in payment of taxes.


Fiat doesn’t hold value because it has fundamentals or inherent utility either.

Fiat currency holds value because it is backed by a sufficiently large group with guns.

Crypto currency holds value because it is backed by a sufficiently large group with encryption.


> Fiat currency holds value because it is backed by a sufficiently large group with guns.

Yep that's what I said: payment of taxes.

> Crypto currency holds value because it is backed by a sufficiently large group with encryption.

I disagree. There is no reason for bitcoin to hold its value. Miners expend real resources (which they pay for) to obtain bitcoin because they speculate that someone will pay more for it further down the line.

People buy bitcoin for the same reason.

The price of bitcoin could go to zero without any compromise of the underlying encryption.

The purchasing power of a currency issued by a soevereign can only go to zero as a result of the collapse of sovereignty (ie. no more guns, or being outgunned). This is the very definition of hyper inflation in terms of a currency: when a government cannot provision itself in exchange for that currency.


> they speculate that someone will pay more for it further down the line

The greater fool is not required when one asset is inflationary and the other is deflationary. A falling denominator is all you need.

> There is no reason for bitcoin to hold its value.

It holds its value for the same reason as fiat. Because the chance of anyone executing a successful attack on it is prohibitively small.

And if someone does, as you said, then it goes to zero.

In your view, how would bitcoin go to zero without a compromise in encryption?


Now what makes bitcoin special and different from any other coin? Take something like Litecoin, far below previous peaks. Surely it is not worse with encryption than bitcoin?


At this point, market cap, i.e. the cost to execute an attack against it.


> In your view, how would bitcoin go to zero without a compromise in encryption?

Everyone realises that it’s worthless and new buyers stop turning up to buy it for more money than the last round of fools


“Actual currency, on the other hand, derives its value from the willingness of the issuing sovereign to accept it back in payment of taxes.”

And yet the purchasing power of the dollar has fallen by 99.5% since moving off the gold standard. Bitcoin claims to hedge against this steady decline in value which is caused by money printing.

If you believe they will stop printing money and diluting the value of the dollar, the argument for Bitcoin fails. If not, Bitcoin’s hard supply cap and perfectly inelastic supply when faced with changes in demand make it a compelling hedge.


If I want to save my money for 100 years I won’t buy bitcoin or hold cash or gold I’ll put it in index funds.


Purchasing bitcoin on any random date in history and holding it for four years or more has outperformed every single index, ETF, stock, commodity, real estate every single time.

Betting on a single index even being around in 100 years is risky. Betting on the dollar lasting 100 years is risky. Betting on Bitcoin lasting 100 years is also risky.

I think looking at 5, 10, or 20 time horizons is more practical and I have high confidence that Bitcoin will continue to be the best performing asset on those time horizons.


Someone is going to get left holding the bag.

The reason I said 100 years is because the US went off the gold standard in 1933 (although it had a weird modified version until the 70s).

There are individual stocks that have been around for over 100 years. The Dow Jones has been around since 1884. Stock exchanges have been around since the 1500s.

Indexes that apply to the averages of top, say, 200 stocks in a given country's econonmy will definitely be there in 100 years, absent a collapse so monumental that money itself has no meaning.

Bitcoin is a freakish sideshow by comparison. Might as well buy baseball cards.


I started learning Mandarin in December with a Taiwanese teacher that teaches at a university in my tiny country. We have classes for an hour and a half every week online. She forces us to read the sentences in simplified characters, not just to know what the pinyin words mean. It's not easy.

I never had any interest in learning an invented language, other than those I use for programming.
