In ongoing work in our lab #HNL, we explore ‘hybrid systems’ of humans & machines. How does addition of AI to our midst affect how we treat each other? New work spearheaded by @MargaretTraeger & Sarah Sebo, along w @dscaz & @whatsmalteupto is just out: pnas.org/content/early/… 1/
In this @PNASNews paper out today, we show that adding a humanoid robot to a social system engaged in a collective problem helps. When the robot makes vulnerable statements, it enhances communication among the humans *themselves*. pnas.org/content/early/… #hbyridsystems 2/
Video of our experimental set-up for our latest @PNASNews paper via @yale is here: news.yale.edu/2020/03/09/rob… 3/
An @TheAtlantic essay about this broad idea regarding human-AI hybrid systems is here: theatlantic.com/magazine/archi… 4/
Prior work of ours, in @nature, showing that adding certain kinds of what we call ‘simple AI’ to social systems can enhance collective problem solving online, is here: nature.com/articles/natur… 5/

People are asking whether patients with COVID19 who don’t have symptoms, e.g. cough or even just fever, can transmit the disease to others. The answer seems to be yes. Alas, this is not good news, but we can still take rational steps. Let’s talk about this. #QuarantineLoophole 1/
Should you avoid getting near symptomatic relatives? Yes, alas. What about college students or travelers returning home who aren't showing symptoms? That’s harder. If they could have been exposed, you should practice social distancing for a while, even if they're asymptomatic. 2/
If people are asymptomatic but have credibly been exposed to COVID19, they should be in home quarantine for 14 days, to be safe. But for how long can someone be asymptomatic and still transmit? It appears that this is on the order of 2-4 days. 3/

Graphs like this are circulating. They are important. We can plot rise in COVID-19 cases & align 'start' of epidemic to some uniform standard (eg, 100 cases), and then use the trajectories to evaluate each country's response and likely future course. USA should be on war footing.
I would like to add, in case it is not clear, that I hope that I (and others) are wrong about this. Perhaps things won't be so bad. But we must look at what was done in China and what is happening in Italy and ask ourselves, why would COVID-19 be any different in USA?
It is hard for many people to intuitively appreciate exponential growth. Nothing seems to be happening for a long time, until a lot happens at once.

If we want to understand how powerful an opponent SARS-CoV-2 (COVID-19) is, let’s take a look what has been required to stop it in China. The Chinese government has essentially used a social nuclear weapon in its efforts. Let’s talk about this, to understand what US is facing. 1/
The Chinese have had the most COVID19 cases so far (80,859), but the number of new cases has dropped from 100's per day a month ago to ~46 per day now — in a country of 1.4B people. This is an astonishing achievement from a public health point of view. who.int/docs/default-s… 2/
We can get a sense of how strong something is by getting a sense of what sort of force is required to stop it, to borrow a Newtonian physics metaphor. COVID-19 requires a powerful force to stop. This is clear from the Chinese response. 3/

The @StanfordHAI (Human-centered #AI) Conference on #AiEthics, Policy, & Governance is getting started, live stream below. Speaker list is fantastic. Will be tweeting.

#machinelearning #data4good
@StanfordHAI "Silicon Valley, we have a problem" opens @erikbryn

Speaks to the 'great decoupling' - where productivity and GDP expand with technology, but don't take household incomes with them.

Part of the problem is lower-paid occupations have more automate-able tasks.
@StanfordHAI @erikbryn Both @Susan_Athey and @erikbryn speaking to ML adoption in private sector and the important distinction between labor replacing vs. labor augmenting #automation.

The "Suitability for Machine Learning" or SML scores from this
@MIT_IDE is useful here: ide.mit.edu/sites/default/… #ai

If you can't simulate and understand biology then you can't overcome the limits of AGI. Well that's the opinion of this paper: researchgate.net/publication/33… #ai
I'm going to argue however that simulating biology is a harder problem than AGI. So I expect AGI to happen before we solve human biology. Kurzweil's immortality will have to wait for AGI to happen.
But why is it that we can bypass the complexity of biology and invent more streamlined general intelligence? That's because biology creates Rube Goldberg like mechanisms. Biology is gratuitously complex.

A longish thread about why fears of the AI apocalypse are way overblown, why these scenarios appeal in particular to a certain kind of narcissistic man, and what to do about it. 1/15
The near-panic that many people—from Stephen Hawking to Elon Musk to Nick Bostrom—have expressed about the possibility of the machines "taking over" or killing off humanity is actually a *displaced anxiety* about the collapse of the distinction between humans and machines... 2/15
...underpinned by three further assumptions: a Darwinian view of nature (including human nature) as an inherently rapacious force; the belief that "the most intelligent wins"; & the idea that humans are the most intelligent creatures, which is why humans have been "winning" 3/15

242. A retelling of "Rebecca" IN SPACE and ALSO GAY VERY GAY
243. A jealous government decrees that all the small household gods residing in the populace's homes and fields must be banished, sending out terrifying agents to slay the little gods. But a young soldier and their friends put up resistance
