He really is a remarkable person. An actor plays a high school teacher who is secretly filmed ranting against government corruption. The secretly filmed video goes viral and the teacher is unexpectedly elected president. Reality ends up mirroring fiction: the clip from the show truly does go viral and the actor who plays the teacher actually gets elected president! But then said actor gets thrown into a war against a superpower and really rises to the occasion. What a remarkable life.
How do people hold yuan? I was surprised at the lack of ETFs in this space. There's of course a lot of Chinese equity ETFs. There used to be a pure currency ETF but it was liquidated a couple years back. CBON seems like a good way to get exposure via bonds, but its AUM is quite low.
> “It is in nobody’s interests for there to be worries and instability in the U.S.,” said Jonathan Haskel, an economics professor at Imperial College Business School and former member of the rate-setting committee at the Bank of England. “Other countries hold lots of American assets. Savers in Europe will implicitly be invested in the American stock market. America is in many ways a flagship engine, with the A.I. revolution going on. Nobody in the world wants to see that at risk.”
Good Judgment Project apparently started in 2011 as part of an IARPA tournament. I first learned about through The Economist, which frequently mentions the crowd consensus on forecasts related to Economist articles.
I stumbled on this work while researching cyborgs. There's quite a bit of jargon on this official page. The main idea (as I understand it) is that previously, when you got an amputation above the elbow (for example) the bicep and tricep muscles became dead ends. They would just attach the ends of the muscles wherever feasible. Apparently the act of one muscle like the bicep contracting (agonist) while another related one like the tricep extends (antagonist) is a really important feedback loop in our brains. AAMI essentially restores this feedback loop, making the prosthetic feel like part of the body. The lead researcher is apparently himself a double amputee.
Osseointegration was another example of interesting real-life cyborg technology that I stumbled upon.
The real magic is the plasticity of the brain, the cerebellum as well as the cortex. In this case, they're tapping in to existing neural structures by correctly aligning the prosthetic with the configuration of the original.
One of the ways the brain works is to construct and predict, or assume, the way things will be, and use proxy signals to confirm the success or failure of a prediction or assumption. By aligning the prosthetic, the proxy signals result in not only successful manipulation of prosthetic orientation and placement, as if it were a foot, but the patient feeling feedback from the prosthetic, as the brain reconstructs some pieces of the sense of actually having a foot.
Phantom limb and phantom pain taps into some of the same phenomena, and advanced prosthetics with myo/neural electrodes actually tap into the nerves and nerve endings to create new input/output pathways, with some experiments actually succeeding at reproducing touch, hot/cold, pressure sensation, and control of the cybernetic limb.
Input is hard, but with nonintrusive ultrasound techniques seemingly working for certain deep brain stimulation, maybe it won't be too long before we see highly precise ultrasound phased arrays able to stimulate precise neurons when installed over a patch of skin, and we'll get wearable third limbs, prehensile tails, and other cyborg augments with full neural io integration for non medical purposes.
Sometimes you get a big price swing but it was on a low volume day. In those cases it's less interesting because it could be just one big buyer pushing the market around. The fact that it was nearly a double digit jump on a single day, and with high volume, is much more newsworthy. It means that a lot of people agreed that silver should be priced 9% higher than it was yesterday. With low volume, the price jump has a higher chance of being a fluke/noise from some uninformed/fringe market participants pricing the asset in silly ways. https://www.investopedia.com/terms/p/pricediscovery.asp
