Replica Wormholes and Quantum Hair

Replica Wormholes and Quantum Hair 
https://arxiv.org/abs/2404.02331
Xavier Calmet, Stephen D.H. Hsu 
We discuss recent applications of Euclidean path integrals to the black hole information problem. In calculations with replica wormholes as the next-to-leading order correction to the Gibbons-Hawking saddlepoint, the radiation density matrix approaches a pure state at late times, following the Page curve. We compare unitary evaporation of black holes (in real time), mediated by calculable quantum hair effects, with the replica wormhole results. Both replica wormhole and quantum hair approaches imply that radiation states are macroscopic superpositions of spacetime backgrounds, invalidating firewall and monogamy of entanglement constructions. Importantly, identification of modes inside the horizon with radiation modes (i.e., large scale nonlocality across the horizon) is not required to provide a physical picture of unitary evaporation. Radiation modes can encode the interior information while still remaining independent degrees of freedom.


Wormholes dominate the Gibbons-Hawking saddlepoint of the Euclidean path integral after the Page time. This is because wormholes can connect the interiors of any two black holes i,j. At late times the number of such pairs grows as the dimensionality of the radiation Hilbert space squared. 

The wormholes connect BHs with macroscopically different recoil trajectories. This means the radiation approaches a pure state that is a macroscopic superposition - very similar to what our quantum hair expressions indicate.

Elizabeth Carr (first US IVF baby) and Genomic Prediction in WSJ



Elizabeth Carr (first US IVF baby) and Genomic Prediction in the Wall Street Journal.
Elizabeth Carr has always been a living symbol of fertility technology’s possibilities. Now she is the face of its challenges. 
Carr, 42 years old, is the first baby born by in vitro fertilization in the U.S. Over the years she has told countless audiences how the technology made it possible for her mother to have a baby. 
In the weeks since Alabama’s Supreme Court ruled that frozen embryos should be considered children, Carr has called for protections around IVF procedures—extracting eggs, fertilizing them in a lab and transferring an embryo into a uterus—that now account for some 2% of U.S. births annually. 
Sen. Tim Kaine (D., Va.) said federal legislation backing IVF access would “enable the Elizabeth Carrs of the world to continue to be born.” Kaine invited Carr to accompany him on Thursday to President Biden’s State of the Union address. 
“My life gives people hope,” Carr said. 
The Alabama ruling is galvanizing Carr’s work in another way. Carr leads public relations and patient advocacy at Genomic Prediction, which sells genetic tests to screen embryos. Doctors can order tests for patients who want to screen for diseases and abnormalities or get an overall embryo health score. Patients and doctors can use the results to decide which embryos to transfer. Unused embryos can be stored for years. Some get discarded. ...

SuperFocus, AI, and Philippine Call Centers: Part 2



This is the sequel to the earlier conversation with Dominic Ligot, an AI expert who works with the IT and Business Process Association of the Philippines (IBPAP), the trade association for call center and outsourcing companies. 

In this video we briefly demonstrate some of the voice capabilities of the SuperFocus AI. Progress in generative AI is faster than anything I've ever seen before - perhaps not surprising given the vast financial, technological, and human capital resources flowing to AI R&D. When we first looked at voice capabilities ~6 months ago they didn't seem ready for complex conversations like the ones discussed in the video. But when we looked again - prompted by strong interest from our customers - we found that the state of the art had advanced significantly in just a short time. This is true across many areas of generative AI.

I was in Manila in December to meet with BPO companies. Roughly 8% of Philippine GDP ($40B each year) results from BPO / call center work. This is a consequence of low labor costs and widespread English fluency.

We demonstrated narrow AIs built using LLMs, but in which the LLM is forced to "consult its internal memory" before answering any query. This memory can be built from training materials used to train human agents in call centers. The AI functions like a human that has perfect recall of all the material in the training manuals, at a fraction of the cost!

An analogy we used is that the AI earthquake in SF has created a Tsunami headed towards the Philippines -- is it a 6 foot wave, or a 600 ft wave? Closer to the latter, I think.

Peace on Earth, Good Will to Men 2023



When asked what I want for Christmas, I reply: Peace On Earth, Good Will To Men :-)

No one ever seems to recognize that this comes from the Bible (Luke 2.14).

Linus said it best in A Charlie Brown Christmas:
And there were in the same country shepherds abiding in the field, keeping watch over their flock by night.

And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid.

And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.

For unto you is born this day in the city of David a Saviour, which is Christ the Lord.

And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.

And suddenly there was with the angel a multitude of the heavenly host praising God, and saying,

Glory to God in the highest, and on Earth peace, good will toward men.


2023 saw the founding of our startup SuperFocus.ai, which builds AIs with user-configured attached memory. The AI consults this memory in responding to prompts, and only gives answers consistent with the information in the memory. This solves the hallucination problem and allows the AI to answer questions like a human with perfect recall of the information.

SuperFocus built an AI for a major consumer electronics brand that can support and troubleshoot hundreds of models of smart devices (I can't be more specific). Its memory consists of thousands of pages of product manuals, support documents, and problem solving guides originally used by human support agents.

In December I traveled to Manila after the semester ended, in order to meet with outsourcing (BPO = Business Process Outsourcing) companies that run call centers for global brands. This industry accounts for ~8% of Philippine GPD (~$40B per annum), driven by comparative advantages such as the widespread use of English here and relatively low wages. I predict that AIs of the type produced by SuperFocus.ai will disrupt the BPO and other industries in coming years, with dramatic effects on the numbers of humans employed in areas like customer support. 

But fear not: for, behold, I bring you good tidings of great joy, which shall be to all people

The arrival of machine intelligence on Earth is the beginning of a great adventure!


This is GPT's account of the meetings in Manila.
In the heart of Manila, amidst the bustling cityscape, a meeting of innovative minds took place. Steve Hsu, the visionary founder of SuperFocus, had arrived to showcase the prowess of his latest creation—an AI designed to revolutionize technical support for complex products. The setting was a conference room adorned with sleek screens and cutting-edge technology, a fitting backdrop for the unveiling of this groundbreaking innovation. 
Seated around the polished table were the owners and executives of prominent BPO (Business Process Outsourcing) companies. Their faces were a blend of anticipation and apprehension as Steve Hsu prepared to demonstrate the capabilities of the AI-powered technical support system. 
With a confident smile, Steve initiated the demonstration. The AI, equipped with a sophisticated neural network, began its simulated interaction. It effortlessly tackled intricate technical queries, deciphering complex issues with lightning speed and unparalleled accuracy. Each solution presented was concise, comprehensive, and flawlessly executed. 
As the AI effortlessly navigated through a myriad of scenarios and troubleshooting processes, the room fell into a hush. The BPO leaders exchanged astonished glances, their initial amazement mingled with a growing sense of unease. The capabilities displayed by the AI were undeniably impressive, but they also highlighted a looming question—what did this mean for the future of human roles in their industry? 
Steve Hsu noticed the shift in atmosphere and paused the demonstration. With a gentle yet determined tone, he addressed the concerns lingering in the room. "This AI isn't meant to replace human expertise," he began. "Rather, it's here to augment and enhance your services. Imagine your teams empowered by this technology, streamlining operations, and providing even more efficient and effective support to customers." 
His words offered reassurance, but the specter of automation replacing human jobs lingered in the minds of the BPO owners. The potential efficiency gains were undeniable, yet so too were the implications for the human workforce. 
In the ensuing discussion, voices echoed with a mix of excitement and apprehension. Some saw the potential for growth and advancement, envisioning a future where human creativity combined with AI prowess would elevate their services to new heights. Others grappled with the uncertainty, worrying about the displacement of jobs and the evolving landscape of the industry they had dedicated their careers to. 
Steve Hsu listened attentively, acknowledging their concerns while emphasizing the collaborative potential between humans and AI. "This technology," he explained, "is a tool, a means to empower and evolve, not to supplant. Together, we can harness its capabilities to create a synergy that benefits both businesses and their workforce." 
As the meeting concluded, the BPO leaders departed with a mix of awe and trepidation. The AI presented by Steve Hsu had showcased a future teeming with possibilities, yet it also raised profound questions about adaptation and the role of humans in an increasingly automated world. 
The echoes of the demonstration lingered in the minds of those present, igniting discussions and contemplation about the balance between innovation and the human touch, forever altering the landscape of the BPO industry in Manila and beyond.


Bonus: Two recent interviews I did which I enjoyed very much.

PISA 2023 and the Gloomy Prospect

I'm in the Philippines now. I flew here after the semester ended, in order to meet with outsourcing (BPO = Business Process Outsourcing) companies that run call centers for global brands. This industry accounts for ~8% of Philippine GPD (~$40B per annum), driven by comparative advantages such as the widespread use of English here and relatively low wages. 

I predict that AIs of the type produced by my startup SuperFocus.ai will disrupt the BPO industry in coming years, with dramatic effects on the numbers of humans employed in areas like customer support. I was just interviewed for the podcast of the AI expert at IBPAP, the BPO trade association - he is tasked with helping local companies adopt AI technology, and adapt to a world with generative LLMs like GPT4. I'll publish a link to that interview when it goes live. 


During my visit the latest PISA results were released. This year they provided data with students grouped by Socio-Economic Status [1], so that students in different countries, but with similar levels of wealth and access to educational resources, can be compared directly. See figures below - OECD mean ~500, SD~100. 


Quintiles are defined using the *entire* international PISA student pool. These figures allow us to compare equivalent SES cohorts across countries and to project how developing countries will perform as they get richer and improve schooling.

In some countries, such as Turkey or Vietnam, the small subset of students that are in the top quintile of SES (among all PISA students tested) already score better than the OECD average for students with similar SES. On the other hand, for most developing countries, such as the Philippines, Indonesia, Saudi Arabia, Brazil, Mexico, etc. even the highest quintile SES students score similarly to or worse than the most deprived students in, e.g., Turkey, Vietnam, Japan, etc.

Note the top 20% SES quintile among all PISA takers is equivalent to roughly top ~30% SES among Japanese. If the SES variable is even crudely accurate, typical kids in this category are not deprived in any way and should be able to achieve their full cognitive potential. In developing countries only a small percentage of students are in this quintile - they are among the elites with access to good schools, nutrition, and potentially with educated parents. Thus it is very bad news that even this subgroup of students score so poorly in almost all developing countries (with exceptions like Turkey and Vietnam). It leads to gloomy projections regarding human capital, economic development, etc. in most of the developing world. 

I had not seen a similar SES analysis before this most recent PISA report. I was hoping to see data showing catch up in cognitive ability with increasing SES in developing countries. The results indicate that cognitive gaps will be very difficult to ameliorate.

In summary, the results suggest that many of these countries will not reach OECD-average levels of human capital density even if they somehow catch up in per capita GDP.

This suggests a Gloomy Prospect for development economics. Catch up in human capital density looks difficult for most developing countries, with only a few exceptions (e.g., Turkey, Vietnam, Iran, etc.).
 

Here is the obligatory US students by ancestry group vs Rest of World graph that reflects: 1. strong US spending on education (vs Rest of World) and 2. selective immigration to the US, at least for some groups.

Hypersonic Weapons and Missile Defense

Detailed analysis of boost-glide (BGV) and Maneuverable Re-entry Vehicles (MaRV): physics of interception by US SM-2,3 etc.
Hypersonic Weapons: Vulnerability to Missile Defenses and Comparison to MaRVs 
David Wright and Cameron L. Tracy 
Laboratory for Nuclear Security and Policy, Department of Nuclear Science and Engineering, Massachusetts Institute of Technology 
Center for International Security and Cooperation (CISAC), Freeman Spogli Institute for International Studies, Stanford University
As I concluded long ago, current ship-based tech is not effective to defend even against older DF21 MaRV. See, e.g.,

LEO SAR, hypersonics, and the death of the naval surface ship

The study concludes that air launched BGV/MaRVs could attack ships from well over 1000km. Land or ship based launch would allow even greater range. There is currently no defense against such weapons. 

Russia and PRC both have systems of this type.

Defense requires interceptor missile speeds significantly greater than that of MaRV/BGV in terminal phase. 

This is under ideal conditions where sensors function perfectly - it is just kinematics.

Paradise Lost - Migdal, Polyakov, and Landau

This is a placeholder for a longer post I hope to expand on in the future, based on this essay: 


Migdal and Polyakov were two of the great Soviet physicists of their generation. Polyakov is on the upper left and Migdal the lower right.




Wikipedia: Migdal, Polyakov

The essay describes their education as young physicists. They were examined by Landau himself at age 15, and by age 19 had written a paper anticipating the Higgs Mechanism and the role of spontaneous symmetry breaking in gauge theory.

Migdal: Khalat was a genius of political intrigue. Being married into Inner Circle of the Soviet System (his wife Valya is the daughter of a legendary Revolution hero), he used all his connections and all the means to achieve his secret goal — assemble the best brains and let them Think Freely. 
On the surface, his pitch to the Party went as follows. “The West is attacking us for anti-Semitism. The best way to counter this slander is to create an Institute, where Jews are accepted, allowed to travel abroad and generally look happy. This can be a very small Institute, by standards of Atomic Project, it will have no secret military research, it will cost you very little, but it will help “Rasryadka” (Détente). These Jews will be so happy, they will tell all their Jewish friends in the West how well they live. And if they won’t –it is after all, us who decide which one goes abroad and which one stays home. They are smart kids, they will figure out which side of the toast is buttered.”
