When GDP became the dominant measure of economies in the 1940s, the internet was still a half-century out. Today, the internet is responsible for a major chunk of economic activity, but GDP misses much of it. This has widened the gap between the closely watched metric and actual economic health.
Why it matters: The problem with GDP is not merely academic — for instance, reliance on the economic benchmark deserves part of the blame for the 2008 financial crisis, according to a 2009 report from a commission led by Nobel laureate Joseph Stiglitz. If economists had been watching other metrics, too, like indebtedness, they would have had an earlier warning of trouble ahead, the commission wrote.
Among the proposed alternatives:
The latest proposal comes from a group of economists led by MIT's Erik Brynjolfsson. In a forthcoming working paper, they propose a measure called GDP-B, adding in the benefits of free digital goods and new technology.
They estimate that hidden benefits from Facebook alone have added 0.05–0.11 percentage points to GDP every year since its 2004 launch. That would have totaled 1.54 percentage points from 2003 to 2017 — a result "too large to be ignored," according to Hulten, who was not involved in this research.
What's next: GDP has solidly hung on despite its critics, but Hulten, who advises the Bureau of Economic Analysis, says the body is now again considering alternatives. "Agencies are very aware of the need to change," he says, but are burdened with a busy schedule — plus many decades of inertia.

A new supercomputer to be built at Argonne National Laboratory in Illinois will be the most powerful in the country when it begins operating in 2021 — more than five times faster the current leader, the Summit supercomputer at Oak Ridge National Laboratory in Tennessee.
Axios Science Editor Andrew Freedman reports: The Energy Department, Intel and subcontractor Cray Inc. announced Monday an agreement worth "more than $500 million" to provide Argonne with the country's first "exascale" computer system.
Why it matters: The transition to exascale computing involves a thousandfold increase in computing power from the petascale systems installed during the past decade, and it promises to open up a broader array of applications, such as precision medicine and AI
Details: The Aurora computer will have the performance of one "exaFLOP," which is equal to a quintillion floating point computations per second, according to a press release and briefing from Intel. The potential uses for this computer include:
Context: There's a race heating up between the U.S. and China for who has the most powerful supercomputer.
"From the perspective of winning the race, it’s not just getting to exascale, but what does exascale get you to that is important. The race matters in terms of stoking innovation. To compete you have to be able to compute."— Raj Hazra, Intel

From 2011 to 2018, the number of millionaires in the world jumped to 42.2 million, from 29.7 million, a 42% leap. But the amount of money spent on art barely increased.
Erica writes: Whether due to geopolitical instability or because the new crop of millionaires just doesn't care about art, sales are lagging, reports NYT. The dollars spent on art was $64.6 billion in 2011. Last year, it was $67.4 billion, a mere 4% increase.
The United States remains the largest market in the world for art, with 44% of the sales. Behind the U.S. is Britain with 21%, then China with 19%.

As we've reported, the world is drinking less booze, and to stay relevant, big distilleries and brewers are pouring money into cannabis drinks, which appear to be the next trend.
Erica writes: But there's one big problem with weed beverages, reports WSJ. They just don't taste that good.
