Gork revisited, 2018

It’s been almost 10 years since I made the post Are you Gork? Over the last decade, both scientists and non-scientists have become more confident that we will someday create: A. AGI (= sentient AI, named “Gork” :-)  See Rise of the Machines: Survey of AI Researchers. B. Quantum Computers. See Quantum Computing at a Tipping …

Low SES does not decrease heritability of cognitive ability (N=300k)

These researchers, from Stanford, Northwestern, and the University of Florida, analyze a large population of twins and siblings (~24k twins and ~300k children in total, born 1994-2002 in Florida). They find no evidence of SES (Socio-Economic Status) moderation of genetic influence on test scores (i.e., cognitive ability). The figure above shows the usual pattern of lower pairwise …

Quantum Computing near a Tipping Point?

I received an email from a physicist colleague suggesting that we might be near a “tipping point” in quantum computation. I’ve sort of followed quantum computation and quantum information as an outsider for about 20 years now, but haven’t been paying close attention recently because it seems that practical general purpose quantum computers are still …

Big Ed

Today I came across a recent interview with Ed Witten in Quanta Magazine. The article has some nice photos like the one above. I was struck by the following quote from Witten (“It from Qubit!”): When I was a beginning grad student, they had a series of lectures by faculty members to the new students about …

Behold, the Super Cow

Hmm… how do they compute the Net Merit and GTPI? (But, but, what about all of that missing heritability?) See also Applied genomics: the genetic “super cow” Genomic prediction: no bull. Attention climate virtue signalers: more efficient cows produce less methane per liter of milk! Drink milk from genetically engineered cows :-) Tweet

23andme

I’m in Mountain View to give a talk at 23andMe. Their latest funding round was $250M on a (reported) valuation of $1.5B. If I just add up the Crunchbase numbers it looks like almost half a billion invested at this point… Slides: Genomic Prediction of Complex Traits Abstract: We apply methods from Compressed Sensing (L1-penalized regression; Donoho-Tanner …

Steven Weinberg: What’s the matter with quantum mechanics?

In this public lecture Weinberg explains the problems with the two predominant interpretations of quantum mechanics, which he refers to as Instrumentalist (e.g., Copenhagen) and Realist (e.g., Many Worlds). The term “interpretation” may be misleading because what is ultimately at stake is the nature of physical reality. Both interpretations have serious problems, but the problem …

Varieties of Snowflakes

I was pleasantly surprised that New Yorker editor David Remnick and Berkeley law professor Melissa Murray continue to support the First Amendment, even if some of her students do not. Remnick gives Historian Mark Bray (author of Antifa: The Anti-Fascist Handbook) a tough time about the role of violence in political movements. After Charlottesville, the Limits …

The Bannon Channel

Rumor has it that Bannon will start a Breitbart TV channel to rival Fox News. Given the success of YouTube- / pod-casters like Joe Rogan (5 million downloads per episode), it’s plausible this could be done with very modest capex (the channel could start out as pure streaming and only go to cable later). Billionaire …

Meanwhile, down on the Farm

The Spring 2017 issue of the Stanford Medical School magazine has a special theme: Sex, Gender, and Medicine. I recommend the article excerpted below to journalists covering the Google Manifesto / James Damore firing. After reading it, they can decide for themselves whether his memo is based on established neuroscience or bro-pseudoscience. Perhaps top Google …

In the matter of James Damore, ex-Googler

James Damore, Harvard PhD* in Systems Biology, and (until last week) an engineer at Google, was fired for writing this memo: Google’s Ideological Echo Chamber, which dares to display the figure above. Here is Damore’s brief summary of his memo (which contains many citations to original scientific research), and the conclusion: Google’s political bias has …

Robots taking our jobs

The figures below are from the recent paper Robots and Jobs: Evidence from US Labor Markets, by Acemoglu and Restrepo.

This effect is distinct from the impacts of imports, …

Natural Selection and Body Shape in Eurasia

Prior to the modern era of genomics, it was claimed (without good evidence) that divergences between isolated human populations were almost entirely due to founder effects or genetic drift, and not due to differential selection caused by disparate local conditions. There is strong evidence now against this claim. Many of the differences between modern populations …

Don’t Touch the Computer

Under what circumstances should humans override algorithms? From what I have read I doubt that a hybrid team of human + AlphGo would perform much better than AlphaGo itself. Perhaps worse, depending on the epistemic sophistication and self-awareness of the human. In hybrid chess it seems that the ELO score of the human partner is …

Genetic variation in Han Chinese population

Largest component of genetic variation is a N-S cline (phenotypic N-S gradient discussed here). Variance accounted for by second (E-W) PC vector is much smaller and the Han population is fairly homogeneous in genetic terms: …while we revealed East-to-West structure among the Han Chinese, the signal is relatively weak and very little structure is discernible …
