This probably deserves it’s own post. The “take home” message is that it doesn’t exist. There is no such thing as “Quantum Computing”.
The “phone book” example that is usually given to explain “Quantum speed up” is just plain wrong. And the reason is simple: You have to transpose the Unitary matrix corresponding to the “Oracle”. And that is O(n) not O(1). Yeah. Embaressing.
It is all a big funding scam. Same as “String Theory” and “Climate Change”.
Everybody knows this to be the case. Some mathematician choose to take the money anyway. So they can stay in “Science”. While others choose to work in the banking sector instead. Where they can make even more money. Both sides believe themselves to be “morally superior”.
From this day forward, my allegiances in the String Wars will be open for sale to the highest bidder. Like a cynical arms merchant, I will offer my computational-complexity and humor services to both sides, and publicly espouse the views of whichever side seems more interested in buying them at the moment. Fly me to an exotic enough location, put me up in a swank enough hotel, and the number of spacetime dimensions can be anything you want it to be: 4, 10, 11, or even 172.9+3πi.
Someday, perhaps, a dramatic new experimental finding or theoretical breakthrough will change the situation vis-à-vis string theory and its competitors. Until then, I shall answer to no quantum-gravity research program, but rather seek to profit from them all.
“It is absolutely impossible for me to hide how intensely I despise people like Scott Aaronson … He’s the ultimate example of a complete moral breakdown of a scientist. It is astonishing that the situation became so bad that the people are not only corrupt and dishonest but they proudly announce this fact on their blogs…” — Luboš Motl.
Get used to it – that’s all I can say. Also. Try to have a sense of humour.
People have a number of misconceptions about Money. For example:
Paper money can be exchanged for gold.
Money is printed by the government.
Rich people are greedy, lying, thieving scumbags.
Let’s go through these one at a time. The gold standard existed throughout most of the British Empire, and was very much intertwined with the notion of “Free Trade”. It was formally abolished on August 15, 1971.
Money is not printed by the government. The government must borrow money from the central bank, and then repay this money by collecting taxes.
The central bank is owned by all the other banks. It is a private institution. Money is created by banks, completely out of thin air, by issuing loans. This system actually dates back to 15th century Florence and is known today as “double entry book keeping”.
You probably have both a “debit card” and a “credit card”. In Latin “debit” and “credit” are the words for Left and Right respectively.
Your debit card balance is the money that the bank owes you. And your credit card balance is the money that you owe the bank.
You have a “ledger” and the bank has a “ledger”.
When you borrow $100 from the bank, the “bank clerk” adds $100 to the credit side of your ledger, and $100 to the debit side of the bank ledger.
Conversely when you deposit $100 into your savings account, the “bank clerk” adds $100 to the debit side of your ledger. And $100 to the credit side of the bank ledger.
It really is that simple. The “scam” is the fact that the bank charges you a much higher interest rate to borrow money, than you get to charge when you lend money to the bank.
Also, the bank lends out about 10 times as much money as it actually has. Or more. Hoping that nobody will notice. You and I are not allowed to loan out money that we don’t have. Because we are not banks.
The biggest difference between between rich people and poor people is that rich people understand how money works, and are able to use debt to their own advantage. While poor people lack access to finance.
Some people in the “developed world” have much greater access to finance than they realize. But they lack basic financial education.
All socialists can do is fantasize about “killing rich people” – and Jews. Which doesn’t actually solve any of their financial problems.
“No amount of violence can ever solve a math problem”
I think it was actually the Babyonians who invented banking. Not the Yehudites. But there is little point arguing with ignorant people.
Trump, for the record, is an “honourary Jew”. That’s why they hate him so much. He grew up not far from Brooklyn and has been doing business with “Lithuanians” his entire life. He even has a town named after him in Israel. And a train station in Jerusalem. You can hate Trump for being rich. Or you can read a book about Real Estate Investment and get rich yourself. The choice is yours.
Rich people aren’t any more greedy or selfish than anybody else. All humans are greedy and selfish. Rich people just have a better strategy for obtaining what their heart most desires. You need a plan to succeed in life. You can’t just wander around at random and hope for the best. It won’t work.
The good news is that you can download pretty much any book on any subject for free from the Russian Library. There is no need to enrol in an expensive university degree in order to get a “financial education”. There are also many resources available on youtube.
Money is power. And there is no excuse for continued ignorance and poverty when all this information is freely available at your fingertips. Just by having an Australian passport you are massively “ahead of the game“.
Obviously, if you are in Yemen or Libya or some place like that – then you have some much more serious problems on your hands.
There is a problem with our banking system that is inherently impossible to fix. And it is this: All loans must be paid back with interest.
The reason for “interest” is that the the lender is taking a “risk” by lending you the money. You might not pay it back at all. So, without “interest” what motivation is there for him to lend it to you in the first place?
Loans that never get paid back are called “delinquent debt”. Sometimes banks and corporations will keep these loans “on the books” as assets – even when they know it is impossible that they will ever get paid. This leads to “zombie corporations” and “zombie banks“.
It is actually impossible for everybody to pay back their debt. Suppose that the bank is offering to lend you $100. An expects you to pay them back $110 at the end of the month. If 20 people take this “deal”. There is now $2000 in circulation.
Everybody is buying and selling things to each other. And at the end of the month, $2200 needs to be paid back to the bank. Somebody is going to fail to pay back their loan.
The banking system is actually a “pyramid scheme”. The old debt can only be paid off with new debt.
The banks are constantly “expanding the money supply” by issuing new debt. There is always more “debt” than “money” in the economy.
In order to keep the ratio of debt to money something reasonable. The only way to do this is to expand the money supply at an exponential rate.
There is no such thing as “sustainable growth”. Built into the very structure of the monetary system itself – the economy must grow exponentially.
