“Quantum speedup is achievable in a real-world system and is not precluded by any hidden physical laws,”
quantum computing power will “grow at a double exponential rate,” besting even the exponential rate that defined Moore’s Law
Dario Gil, head of IBM Research, described the experiment as a highly special case “laboratory experiment” that has “no practical applications.” He added, “Quantum computers will never reign ‘supreme’ over classical computers, but will rather work in concert with them, since each have their unique strengths.”
Jim Clarke, Intel Labs’ director of quantum hardware, called Google’s update “a notable mile marker.” He said that “a commercially viable quantum computer will require” many R&D advancements before becoming a reality.

“There’s a widely held misunderstanding that genocide is the scale of extermination of human beings,” said the former UN human rights envoy Ben Emmerson QC. “That’s not so. The question is: is there an intention to, if you like, wipe off the face of the Earth a distinct group, a nation, a people?” This, Emmerson and Barack Obama’s former CIA director Leon Panetta claimed, is what is happening to the Islamic people of Xinjiang. “This is a calculated social policy designed to eliminate the separate cultural, religious and ethnic identity of the Uighurs,” said Emmerson. “That’s a genocidal policy.”
Are we so in thrall to consumerism, to buying cheap goods made by cheap labour in China, so intimidated by Chinese military and economic might, that we connive with what may well amount to a criminal dictatorship? The Chinese refer to the 19th century, during which the British oppressed them with two opium wars, as the Century of Humiliation. Ours is becoming the Century of Moral Feebleness.

[1908.08168] Intra-day Equity Price Prediction using Deep Learning as a Measure of Market Efficiency
In finance, the weak form of the Efficient Market Hypothesis asserts that historic stock price and volume data cannot inform predictions of future prices. In this paper we show that, to the contrary, future intra-day stock prices could be predicted effectively until 2009. We demonstrate this using two different profitable machine learning-based trading strategies. However, the effectiveness of both approaches diminish over time, and neither of them are profitable after 2009.
this would be a massive sea change in american-style capitalism. though whether it's genuine and going to lead to actual differences in behaviour is quiet debatable. as the article concludes, quoting Andy Green from Center for American Progress, “We need to see the details to see if they put their money where their mouth is.”
"The change amounts to a call to reform capitalism in a time in which rising populism and concern about climate change have led politicians and shareholder activists to demand that companies consider their impact on the world beyond their balance sheets.
It is a significant departure from the bedrock belief that businesses serve the owners of their capital — a philosophy championed by Nobel Prize-winning economist Milton Friedman and which has driven corporate America for decades."

“The recent escalation in US-China tensions reinforces our view that trade and geopolitical frictions have become the key driver of the global economy and markets,” BlackRock, the world’s biggest asset manager, said earlier this week.

“Beating them to a pulp is not enough,” one person said about protesters on Tuesday, echoing an increasingly common sentiment on Weibo. “They must be beaten to death. Just send a few tanks over to clean them up.”
“The five-star flag has 1.4 billion guardians,” CCTV wrote indignantly to its 87 million followers on Weibo. “Repost! ‘I am a guardian of the flag!’ ”

profit motive destroys long-term value and favours capital over labour
"For the first time, the nonfinancial corporate business sector now consistently spends more on acquiring financial assets than on capital development."
"Rising out of the economic stagnation of the 1970s, shareholder primacy theory refocused corporate management’s understanding of economic value as financial return to shareholders. This theory tilts business decision-making towards returning money quickly and predictably to investors rather than building long-term corporate capabilities, reduces investment in research and innovation, and undervalues American workers’ contribution to production."
moving beyond the profit motive
"The signs of this new post-supply side era are all around us. Witness the rise of the B-corporations, which balance purpose and profit, and the growth of investing based on environmental, social and governance factors."
AlphaStock fully exploits the interrelationship among stocks, and
opens a door for solving the “black box” problem of using deep learning models in financial markets. The back-testing and simulation experiments over U.S. and Chinese stock markets showed that
AlphaStock performed much better than other competing strategies. Interestingly, AlphaStock suggests buying stocks with high long-term growth, low volatility, high intrinsic value, and being
undervalued recently.
