Quantum Hair and Black Hole Information, University of Amsterdam, 17 Jun 2022

 

As promised, video from my talk in Amsterdam. 

Seminar at the Institute of Physics, University of Amsterdam, 17 Jun 2022. 

Title: Quantum Hair and Black Hole Information 

Abstract: I discuss recent results concerning the quantum state of the gravitational field of a compact matter source such as a black hole. These results demonstrate the existence of quantum hair, violating the classical No Hair Theorems. I then discuss how this quantum hair affects Hawking radiation, allowing unitary evaporation of black holes. Small corrections to leading order Hawking radiation amplitudes, with weak dependence on the external graviton state, are sufficient to produce a pure final radiation state. The radiation state violates the factorization assumption made in standard formulations of the information paradox. These conclusions are consequences of long wavelength properties of quantum gravity: no special assumptions are made concerning short distance (Planckian) physics.

Amsterdam, Utrecht, Split, Hvar

Last week I was in Amsterdam and Utrecht to give seminars on quantum hair and black hole information at the Universities of Utrecht and Amsterdam. The organizers told me I was the first external visitor to give an in-person talk since the COVID lockdowns. 

The Utrecht seminar went over 2 hours (unfortunately, 't Hooft was away) and the other over 90 minutes. 

I will post video of the seminars at some point. 

Now I am at the John Bell Institute on Hvar, Croatia for a special workshop on the black hole information puzzle

Future Investment Initiative (Riyadh)

I'm making my way home from the FUTURE INVESTMENT INITIATIVE 2019 in Riyadh, Saudi Arabia​​​. At the moment I am sitting in a Lufthansa lounge at Frankfurt.

The annual event is sponsored by the Saudi sovereign wealth fund, or PIF (Public Investment Fund), which is one of the largest pools of capital in the world.

The meeting this year had an AI theme, and I spoke in the AI and Health (genomics) session. The mix of people was very interesting -- VC, hedge fund, and private equity investors (among other things, looking for allocations from PIF), tech entrepreneurs, policy and government people, etc. There was a large Chinese contingent at the meeting, and a strong Huawei presence. IIUC the telco infrastructure in the Kingdom uses a lot of Huawei gear.

I got a Star Wars cantina in business suits vibe from the thousands of attendees at the Ritz. The various global tribes were there in almost equal mixture -- Americans (Silicon Valley + NY money), Euro-grifters, money men, technologists, spooks, government suits, Chinese, Arabs, Indians, Russians (even Sputnik News). The Kingdom is really at the global crossroads.

Right away on the first day I "bumped into" someone from the US embassy. Her card says State, but I suspect another agency with three letters.

My hotel was in the DQ or Diplomatic Quarter, not far from the Ritz. The DQ is separated from the rest of the city by serious security checkpoints. The Saudi soldiers like to wear their pistols low on the thigh with cool looking black polymer "gunfighter" holsters.

Our panel on AI and Health was held here:

My speaker pass. I had a driver and was able to get through the numerous security checkpoints quickly using this. MBS has his own elite Royal Guard, and they were in evidence at the event.


Over the summer I also spoke at the Tallinn Digital Summit and the World Congress of Information Technology in Yerevan Armenia -- lots of travel! I haven't even had time to blog about these events. There are videos of my talks and panels I will try to post at some point.

London and Tallinn


I'll be speaking about AI and Health in Tallinn, after a stop in London to help the Tories prepare for the upcoming general election ;-)
Tallinn Digital Summit is where the frontrunners of digital nations drive the global conversation on digitalization.

Over the course of a day political leaders, policy innovators, thought-leaders, entrepreneurs and tech-community spotlight the most topical matters of digital transformation and tackle questions about its implications on economies, societies and governments. TDS is an annual meeting place for enhancing practical sharing of ideas and lessons to chase the opportunities of digital transformation for economy, e-governance development as well as societies. Also, to shape a more coherent approach to challenges brought by digital transformation.

Being one of the most digitally advanced countries, Estonia is an ideal location for the event. It has significant experience in building a digital society and economy, having built its digital core on secure distributed architecture. The country is also an outsized creator and exporter of startups, and possesses considerable cybersecurity expertise. Tallinn also hosts the HQ of NATO Cyber Defence Centre of Excellence and the European Agency for the Operational Management of Large-Scale IT Systems.

The diffusion of knowledge

Szilard and Wigner told Einstein about their recent calculations... how the fission process might create chain reactions and nuclear bombs. "Daran habe ich gar nicht gedacht," said Einstein -- I did not think about that at all!
In the past two weeks I gave talks at ISIR2019 (Minneapolis), the Institute of Biomedical Sciences (Academia Sinica, Taipei -- home of the Taiwan biobank), Innovative Genomics Institute (IGI = CRISPR central, UC Berkeley and UCSF) and at OpenAI (AGI in San Francisco).
Title: Genomic Prediction of Complex Traits and Disease Risks via AI/ML and Large Genomic Datasets

Abstract: The talk is divided into two parts. The first gives an overview of the rapidly advancing area of genomic prediction of disease risks using polygenic scores. We can now identify risk outliers (e.g., with 5 or 10 times normal risk) for about 20 common disease conditions, ranging from diabetes to heart diseases to breast cancer, using inexpensive SNP genotypes (i.e., as offered by 23andMe). We can also predict some complex quantitative traits (e.g., adult height with accuracy of few cm, using ~20k SNPs). I discuss application of these results in precision medicine as well as embryo selection in IVF, and give some details about genetic architectures. The second part covers the AI/ML used to build these predictors, with an emphasis on "sparse learning" and phase transitions in high dimensional statistics.
Slides for the first part of the talk.

I also appeared on Dilbert creator Scott Adams' show.

Beijing 2019 Notes

I'm at Beijing University in Zhongguancun. Some brief notes and photos below.

I had meetings with Beida professors, prominent tech entrepreneurs and VCs, policy analysts, IVF doctors and genetic scientists. I also had conversations with ordinary people -- drivers, maids, hotel and service staff.

I've been traveling to Beijing for about 15 years now and have observed significant improvements in infrastructure, general economic level, civil society, general behavior. This would of course be obvious to people living in China, which presumably explains the confidence people here have in their government and in continued advances in development. The hypothesis that this society is "brittle" or vulnerable to shocks seems unsupported.

The main thing to comprehend about China is scale. There are easily ~350M (i.e., population of US) people here living roughly first world lives: with access to education, good jobs, climate controlled apartment in major city, good public transportation, fast internet access, etc. Probably the number is twice as large depending on how one defines the category. For one thing, this means that the supply of engineers, technologists, lab scientists, project managers, entrepreneurs, etc. is very large. There are certainly poor people who lack opportunity, but the size of the population for which the education and economic system are working reasonably well is very large. Possibly a billion people out of ~1.4B.

Beijing is a microcosm of this phenomenon of scale. It's a huge city (over 20M people) with the kind of modern metro system only to be found in places like Tokyo or perhaps Seoul or Paris or London. One can ride the longer lines for 90 minutes without exiting, covering the entire extent of the city from one side to the other. Despite the public transport system, the roads are clogged with recent model cars, producing traffic conditions reminiscent of Los Angeles. I don't find the city as a whole all that livable -- it's too enormous for me -- but locals know all the many charming locations (see photos below). Beijing is reaching a level of development that reminds me of Tokyo.

Trump, the trade war, and US-China relations came up frequently in discussion. Chinese opinion tends to focus on the long term. Our driver for a day trip to the Great Wall was an older man from the countryside, who has lived only 3 years in Beijing. I was surprised to hear him expressing a very balanced opinion about the situation. He understood Trump's position remarkably well -- China has done very well trading with the US, and owes much of its technological and scientific development to the West. A recalibration is in order, and it is natural for Trump to negotiate in the interest of US workers.

China's economy is less and less export-dependent, and domestic drivers of growth seem easy to identify. For example, there is still a lot of low-hanging fruit in the form of "catch up growth" -- but now this means not just catching up with the outside developed world, but Tier 2 and Tier 3 cities catching up with Tier 1 cities like Beijing, Shanghai, Shenzhen, etc.

China watchers have noted the rapidly increasing government and private sector debt necessary to drive growth here. Perhaps this portends a future crisis. However, I didn't get any sense of impending doom for the Chinese economy. To be fair there was very little inkling of what would happen to the US economy in 2007-8.  Some of the people I met with are highly placed with special knowledge -- they are among the most likely to be aware of problems. Overall I had the impression of normalcy and quiet confidence, but perhaps this would have been different in an export/manufacturing hub like Shenzhen. [ Update: Today after posting this I did hear something about economic concerns... So situation is unclear. ]

Innovation is everywhere here. Perhaps the most obvious is the high level of convenience from the use of e-payment and delivery services. You can pay for everything using your mobile (increasingly, using just your face!), and you can have food and other items (think Amazon on steroids) delivered quickly to your apartment. Even museum admissions can be handled via QR code.

A highly placed technologist told me that in fields like AI or computer science, Chinese researchers and engineers have access to in-depth local discussions of important arXiv papers -- think StackOverflow in Mandarin. Since most researchers here can read English, they have access both to Western advances, and a Chinese language reservoir of knowledge and analysis. He anticipates that eventually the pace and depth of engineering implementation here will be unequaled.

IVF and genetic testing are huge businesses in China. Perhaps I'll comment more on this in the future. New technologies, in genomics as in other areas, tend to be received more positively here than in the US and Europe.

Tiananmen Square (see below for historical note)


An email sent to Julian Assange's attorney, whom I met at CogX in London:
Hi Jen,

I really enjoyed your Q&A today. Keep fighting the good fight.

Wikileaks diplomatic cables reveal no mass shootings in Tiananmen Square:

https://wikileaks.org/plusd/cables/89BEIJING18828_a.html

https://www.telegraph.co.uk/news/worldnews/wikileaks/8555142/Wikileaks-no-bloodshed-inside-Tiananmen-Square-cables-claim.html

Our media has been misrepresenting this historical event for 30 years
now. There was certainly violence, but not in the square itself.

Best wishes,

Note Added: In the comments AG points to a Quora post by a user called Janus Dongye Qimeng, an AI researcher in Cambridge UK, who seems to be a real China expert. I found these posts to be very interesting.

More recommenations: Bruno Maçães is one of my favorite modern geopolitical thinkers. A Straussian of sorts (PhD under Harvey Mansfield at Harvard), he was Secretary of State for European Affairs in Portugal, and has thought deeply about the future of Eurasia and of US-China relations. He spent the last year in Beijing and I was eager to meet with him while here. His recent essay Equilibrium Americanum appeared in the Berlin Policy Journal. Podcast interview -- we hope to have him on Manifold soon :-)

Ditchley Foundation Conference: The intersection of machine learning and genetic engineering


I'll be back in the UK soon for the meeting described below. Above, Ditchley House.
The intersection of machine learning and genetic engineering: what should be our check list for society and state as we blast off?

07 - 09 FEB 2019

Advances in machine learning and genetic engineering are combining to produce rapid advances in medicine, development of materials and genetic engineering. Parallel advances in robotics and automation have made the practical process of gene editing scalable. The possibility exists that advances in quantum computing could further accelerate progress on machine learning, bringing a second boost to this technological rocket.

This Ditchley conference will bring together an unusual mix of deep expertise and scientific renown in the disciplines; thinkers on religion, ethics and law; investors fueling innovation; and political leaders looking to shape the approach of society and state to fast emerging possibilities. We will attempt to establish sufficient common understanding of what the science promises and what it doesn’t and then explore the opportunities and risks that are likely to unfold at speed. This will be a first pass at preparation for potential blast off – what should be our moral, legal, economic and national security checklist as we wait on the launch pad of a new age?

The progress on machine learning is quite narrow in scope – deep learning using neural networks and other techniques on large data sets that now exist that didn’t previously and that are store-able and computable in a way that was not possible previously. But whereas progress towards general AI is often overstated, full general AI is not required to radically accelerate gene sequencing, editing and programming, with costs falling all the time and scale and speed increasing.

We will examine and try to come to preliminary conclusions on questions such as the following:

How should the most aggressive genetic engineering technologies be regulated?

How can societies best assess the ethical issues raised by these technologies to find an optimal balance between fostering genetic technologies for the common good while preventing abuse?

What are the implications for the global economy and economic cooperation and competition between states? Are we entering a period of bio-nationalism as well as AI nationalism? Should this be compared to the space race of the Cold War? How can we avoid competition between states driving abandonment of norms and moral standards? What will be the impact on the labour force of the new combined technologies of AI and bio-engineering? Within countries, will potential applications of the new technologies further intensify the concentration of wealth and power in a few hands?

What are the implications of rapid combined advances in AI and bioengineering for defence and national security? Will countries be tempted to pursue military applications either through bio-weapons or through the genetic improvement of military forces? What new materials will emerge and how will they affect the balance of power in warfare?

What are the implications for medicine and public health? If we are able to find targeted genetic cures for diseases like cancer then what will the impact be on the population? What are the implications for ageing or declining populations?

How should we handle the implications of deeper knowledge about the influence of our genes on our characteristics and on the characteristics of groups? How do we chart a course between remaining scientifically objective and providing material that could be misused to support racist conclusions by those tending to that view?

What opportunities and threats are there in the potential of these combined technologies for democracies and the equal value put on the view point of each citizen in the electoral system and the rule of law? More philosophically, how can we make sure the development of these technologies contributes to a positive sense of human progress and meaning, rather than to a sense of alienation and loss of purpose? How can we manage the tension between science and religion as human capability to shape the genetic world increases?
I'm only briefly in London on my way there, but might be able to squeeze in a few meetings :-)

Slate Star Codex Meetup -- Berkeley

I will be at this meetup later today:
BAY MEETUP 1/6 UPDATE

POSTED ON JANUARY 4, 2019 BY SCOTT ALEXANDER
Due to rain, we’re switching to holding the meetup indoors at 3045 Shattuck Ave, Berkeley, 94705. There will be several floors of space available for overflow, so hopefully it won’t be too crowded. Thanks to Claire, REACH, and Event Horizon for setting this up.

Time is still 3:30 PM on Sunday, 1/6. There’s also a Facebook event here.
For the unfamiliar, Slate Star Codex is one of the best blogs on the planet, with a large devoted following of rationalists. Scott is an incredibly talented writer and thinker, and I envy him his readership and commentariat :-)

The Golden State

Apologies for the lack of posts. I've been enjoying some time with the family in CA :-) Kids have the MI middle school state swimming championships coming up and we got some good training done in a beautiful outdoor pool. I'm using USRPT methods, which seem to work well for my kids. I wish we had it when I was competing.

We had really good luck with the weather, sunny and 60s every day on the central coast.




Now I'm in the bay area for this meeting:

London / DeepMind photos

I've been very lucky with the London weather on this trip -- in the 50s and sunny.



These were taken from the roof terrace of the Google building that houses DeepMind:





These are from the nearby area: St. Pancras, Granary Square, in King's Cross.







More photos from the area.


Photos below from The Economist (also rooftop views of London, but not as posh as GOOG) and BBC visits.

This Economist article on Genomic Prediction has been in waiting for weeks, to appear in The World in 2019 special issue. I spent a couple hours briefing their science team on what is coming in AI and genomics -- I would guess there will be more coverage of polygenic scores and health care in the future.

See also this New Scientist article on GP.

2019 may be the Year of the Designer Baby, if journos are to be believed ;-)  Of course, this is sensationalism. It is more accurate to say that 2019 will see the first deployment of advanced genetic tests which can be used to screen against complex disease and health risks. Already today ~1 million IVF embryos per year are screened worldwide using less sophisticated genetic tests for single gene disease mutations and chromosomal abnormality.

The Economist:
In 2019, ... those with the cash to do so will have an opportunity to give their offspring a greater chance of living a long and healthy life.

"Expert" opinion seems to have evolved as follows:
1. Of course babies can't be "designed" because genes don't really affect anything -- we're all products of our environment!

2. Gulp, even if genes do affect things it's much too complicated to ever figure out!

3. Anyone who wants to use this technology (hmm... it works) needs to tread carefully, and to seriously consider the ethical issues.

Only point 3 is actually correct, although there are still plenty of people who believe 1 and 2   :-(
BBC wanted me for their Radio 4 Today show. I went in and recorded some clips, but the broadcast may be delayed due to all the Brexit excitement -- Theresa May has finally revealed the proposed EU-UK agreement her administration negotiated. Angry Brexiteer Tory MPs may vote her out. I had a ringside seat to all this thanks to my friend Dominic Cummings!
