Right now we at at a point where we are experimenting with some new 
mythologies.  Yes they may well have real impacts, they are already having real 
impacts.  And expect our financial overloads to be on the attack.

We already have that.  We already have cash, and have had it for a long time.  
And cash is good for the whole gamut of human activities so far. Nice and 
nasty.  Are you arguing against cash?  Because our financial overlords agree 
with you and want to be able to control and see (and get a percentage), of 
every transaction you make.  They can't do that with cash although they can do 
it to some extent with bitcoin but not necessarily other cryptocurrencies.

Currencies experience fluctuation in value but the fluctuations of bitcoin
are in a different league to virtually any other currency fluctuation.  BUT
THIS IS NOT AN ARGUMENT FOR BITCOIN!   This is an argument for judicious
currency management and controls that armour currencies against
speculators.  The Asian currency crisis in 1997 involved large swings in
currency value - though way less than the range of bitcoin - and resulted
in massive economic loss and hardship.  It might be easy to "whatever" this
sitting in a country with a robustly managed currency but there was
enormous and widespread loss of wealth and livelihood in affected Asian
countries.  For example (Wikipedia):

"Thailand's booming economy came to a halt amid massive layoffs in finance,
real estate, and construction that resulted in huge numbers of workers
returning to their villages in the countryside and 600,000 foreign workers
being sent back to their home countries. The baht devalued swiftly and lost
more than half of its value. The baht reached its lowest point of 56 units
to the U.S. dollar in January 1998. The Thai stock market dropped 75%.
Finance One, the largest Thai finance company until then, collapsed."

This is a key point and one which banks, the gatekeepers of money transfers 
dislike because they do not get their cut of inter-currency transfers. 
None-the-less, if cryptocurrency has only this use it is a pretty decent use.

I'm not sure this is the case.  The rising value of bitcoin has pretty much 
matched its uses in China as a way for Chinese to get around government 
restrictions on moving RMB to foreign currencies.  The transaction amounts of 
that has overshadowed all the other things happening.  Now that China has 
started banning cryptocurrencies and exchanges, that will probably settle down. 
 But any currency that has major influxes of other currencies flowing into it 
will have similar volatility.

Blockchain is not the most important innovation this century, let alone

It is an interesting idea which will likely be applied to some useful

off the whole thing.


As an example, blockchain might be applied to education:

On the contrary, to have any kind of trust that is not based on government is 
pretty amazing.

Well, people have been.  Mostly Chinese people.

I'm not sure anyone uses bitcoin for that at the moment, it takes too long.
Monero is the current cryptocurrency of choice for that, I believe.

As long as the total value of any kind of currency is small, it is going to be 
volatile.  That will never change.  It's why people like Soros can destabilise 
a whole nation's currency.  It's why your US currency is so stable.  
Effectively stable cryptocurrencies have already appeared.

You should have heard them all gushing. Adrian whosits from CSIRO Data61 was as 
well, mostly about secure communications, and not currency in particular. But 
all I kept thinking was, "and you work for a government agency?", remembering 
all the fuss Defence Signals put up over even strong encryption. It's like 
these guys don't talk to each other and it takes us'ns on the outside seeing 
the larger picture to point this out to them.

Of course I found it suss when Berg was gushing, Mr Libertarian who is now

he sports Dr now in public, and RMIT. It all was just too bizarre, like I'd

Would he know?  The blockchain has great appeal to libertarians because it
doesn't, or apparently  doesn't, require government management control to
work (and, as we all know, government is the real evil.)

However, the practical reality of bitcoin is a running disaster.  Could
anyone commit to a major investment on bitcoin financing?  Would you take a
two year loan in bitcoins, repayable in bitcoins?  You might as well go to
the local casino and drop your cash on black.  It works for drug deals but
anything long term?  I think not.

While it is certain that stable working virtual currencies will appear, it
is completely unnecessary for them to be blockchain-based.  The blockchain
mechanism is mainly desirable because it requires no central authority.
However, a reliable currency is tied to a reliable government.  The US
dollar is not a reliable currency because it is a cool idea (though it is a
cool idea.)  It's fundamental basis is that the US government requires
taxes to be paid in US dollars.  As long as the US government collects
taxes and goes after anyone who misuses the currency - eg by stealing it or
printing their own notes - the value of US dollars is assured.  Moreover,
it value is loosely constrained to the value of the goods and services that
it represents.  (Unlike bitcoin's value which is basically an emotionalized
fantasy.)

Interesting article on government-backed virtual currencies:

https://bankunderground.co.uk/2017/09/13/beyond-blockchain-what-are-the-technology-requirements-for-a-central-bank-digital-currency/

Blockchains have other potential uses for secure distributed communications
but they are unweildy and, even while the chain itself may be wonderfully
secure, that's not how hacking hacks stuff.  It goes after the breakable
parts.

Methinks that CB may be engaging in a bit of futurology.  It's historical
