TED talk notes: Nick Hanauer’s famous banned talk on the rich and Clio Cresswell on math + sex

Listening to TED talks was a regular habit of mine. I’m slowly publishing the notes, to share with readers and as a personal refresher. Here’s the full list of notes.

This week we have a talk from Nick Hanauer (one of the infamous banned talks) on why rich people don’t create jobs, and from Clio Cresswell on the link between math and sex.

* * * * *

Nick Hanauer: Rich people don’t create jobs

  • the rich aren’t job creators, supply side economics is false
  • consumers are king, consumers create jobs
  • hiring is a last resort for capitalists. to call capitalists job creators is disingenuous
  • rich people may consume more, but it’s not commensurate with their higher earnings
  • look at recent decades: as taxes on rich and capital gains have gone down, unemployment has stayed high, real incomes for middle and lower class have stagnated
  • to raise taxes on the rich benefits everyone long-term
  • help the middle class prosper, and create jobs for everyone

Mathematics and sex | Clio Cresswell

  • there are equations that predict with 95% accuracy whether spouses will stay together over time, includes data on in-laws and body language
  • couples that compromise the LEAST ended up staying together the longest
  • maybe having high standards, finding ways to reach for them, is the way to go
  • mathematics is used in many fields: from creating chocolate to optimizing antibiotics to predicting political elections
  • men overestimate their # of past sexual partners, but estimation as a process usually leads to over-guessing (her favorite clue in the data: 80% of self-reported men’s numbers were divisible by 5!)
  • testosterone peaks in morning, slumps in the evening, and cycles every 2 to 2.5 hours
  • rats can count approximately, but can’t do exact because they don’t have a linguistic / mental representation of numbers. we’re the same: if we can’t count out a sequence, we can only do approximations, too

TED talk notes: Jill Tarter on the search for aliens and Noah Feldman on Islam as technology

Listening to TED talks used to be a regular habit of mine. So periodically, I publish some of those notes. It’s both a personal refresher and a chance to share valuable knowledge with readers. Here’s the complete list of TED notes.

This week we have talks from Jill Tarter on the search for alien life and Noah Feldman on Islam as a technology.

* * * * *

Jill Tarter: Why the search for alien intelligence matters

  • “we live on a fragile island of life”
  • “if we’re alone…incredible waste of space”
  • discovering other cultured civilizations could strengthen humanity’s bonds with each other
  • “we’re a billion year lineage of wandering stardust”
  • SETI began 50 years ago, it’s the archaeology of the future (given speed of light)
  • our sun is one of 400 billion stars in the Milky Way galaxy, and the Milky Way is only one of 100 billion other galaxies (!)
  • the more we learn the wider our “livable space” becomes (e.g., the more stars, the more species in extreme environments we’ve discovered just on Earth)
  • on Earth life happened quickly. the majority of time (90+%) has been spent developing and evolving life, not waiting for it to arise
  • Copernican revolution changed our thinking in many areas (astronomy, physics, theology). Finding alien life would be comparable
  • Drake conducted the first SETI observation of distant stars
  • Paul Allen and Nathan Myrhvold are generous supporters
  • “we all belong to one tribe, Earthlings”

* * * * *

Noah Feldman: Politics and religion are technologies

  • politics and religion are analyzable as technologies, via conceptual design
  • democracy is a technology to channel power from many into the hands of a few
  • Islam is a means of construing the universe as way to bring salvation to its followers and to achieve goals such as peace, justice, equality as viewed within its doctrine
  • “because they’re technologies, they’re manipulable”
  • democracy and Islam are portrayed as incompatible, but technologies are more malleable than that
  • an Egyptian group of activists were blocked from forming a party which presented as combination of democracy and Islam

TED talk notes: Nick Bostrom on what happens when computers become smarter than us

Every week, I share my notes from great TED talks. Here’s the complete list (sorry, it takes awhile to load).

This week features two talks from Nick Bostrom on super intelligent computers. One is a TED talk and the other is an author talk @ Google.

* * * * *

Nick Bostrom: What happens when our computers get smarter than we are?

  • human brains are largely similar to those of apes (only in the last 250K-1M years did ours begin to differ)
  • AI used to be commands in a box
  • now there’s a paradigm shift, today it’s about machine learning, about algorithms that learn from raw data like an infant
  • because of this, AI is not domain-limited
  • machine substrate is hands down superior to biological tissue: no speed or size limitations
  • AI will evolve similarly to human intelligence: it took animals millions of years to develop basic intelligence, but complex intelligence developed faster by orders of magnitudes(“AI train won’t stop at human…will swoosh right by”)
  • believes super intelligence will have preferences and will – to some extent – get what it wants
  • what are those preferences?
  • we must avoid anthropomorphizing (ie, we can’t assume it wants what people want)
  • there will be unintended consequences no matter what goals we specify (eg, say we ask it to solve a math problem, and it realizes the best solution is re-organize the planet into a giant supercomputer to solve the problem!)
  • mentions the King Midas myth (everything he touched turned to gold)
  • what we should do now is specify precisely our constraints, goals, and design principles to guide AI’s development

* * * * *

Nick Bostrom: “Superintelligence”

  • how do we control AI?
    1. control and limit its capabilities – for example, only allow it to exist in a box with no ethernet, or only print output on a screen. but to realize its full potential, you must give it full access, and super intelligence can by definition outsmart you
    2. control its motivation – change its motivations, preferences, and end-goals
  • the difference between normal risks (e.g., war) and existential risks (e.g., give everyone the ability to make and detonate a nuclear bomb)
  • AI/superintelligence is an existential risk
  • “we only get one shot at it…but humans are mostly bad at getting things right the first time”
  • we need to develop control mechanisms, the right ways to think about and constrain and optimize the problem, before AI gets ahead of us
  • when asked by experts to estimate the median years until development of human-level machine intelligence, estimated 40 years (2050)

TED talk notes: Robert Neuwirth on our informal economy and Chrystia Freeland on the super rich

Every week, I share my notes from great TED talks. Here’s the complete list (it takes awhile to load).

This week we have Robert Neuwirth on the informal (mostly untaxed, unregulated) economy and Chrystia Freeland on a rise in the super rich.

* * * * *

Robert Neuwirth: The power of the informal economy

  • Lagos — no streets for stores, so lady sells stuff from boat, comes to your home
    • garbage dump — 2K people work there scavenging materials
  • “alif” — a place in the world where everything exists (e.g., imagine a hyper-crowded flea market next to a camp)
  • he calls this System D — the DIY economy, the economy of self-reliance; government hates DIY
  • we’re focused on the “luxury economy” ($1.5T market) but this excludes 2/3 of the world’s workers
  • P&G’s largest market segment is actually the informal economy: tiny stores, street hawkers selling detergent (and it’s the only segment that’s growing)
  • Nigeria is the “big dog in Africa” — 1 in 7 Africans are Nigerian
    • M-Tel — only sells airtime, sells through street vendors
    • tons of Guangdong (China) phones going to Nigeria
  • for large brands, “piracy is research” — not going to buy their products anyway, and lets them learn where their products are hot
  • Siemens paid $2B in bribes, yet we demonize the little guys

* * * * *


Chrystia Freeland: The rise of the new global super-rich

  • as income inequality increases, social mobility decreases
  • today we live in the era of superstars in every industry — even dentists!
  • while the rise in the top 1%’s wealth is astonishing, rise in 0.1% is even more extreme
  • how GM employs 100K, FB only employs thousands
  • today productivity increases are decoupled from wage increases

TED talk notes: did you know humans have fewer genes than rice? (talks from John Lloyd, Andrew Hessel, Robert Full)

Every week, I share my notes from great TED talks. Here’s the complete list (pardon the load time, it’s a long page).

Here are 3 sets of brief notes: producer John Lloyd on what’s invisible, researcher Andrew Hessel on synthetic viruses, and biologist Robert Full on the secrets of animal movement.

* * * * *

What’s invisible? More than you think – John Lloyd

  • we can’t see gravity. it’s the weakest and least understood of our 4 fundamental forces
    • the other three are strong and weak, nuclear
    • me: interestingly gravity is the only one you “feel”
  • we can’t see consciousness
  • Sufi masters say they’re all telepaths
  • initially we thought there were 100K genes in the human genome, continually revised downward, now think only 20K genes
    • rice by comparison has 38K genes (!)
  • every cell in your body is replaced at some point, after 7 years all have been replaced
  • we can’t see beam of light, only what it hits
  • we think there are 100B galaxies but can only observe 5
    • me: one of may reasons why I think there MUST be alien life
  • Thomas Edison: “we don’t know one percent of one millionth about anything”

Synthetic virology | Andrew Hessel | TEDxDanubia

  • the Pink Army Movement is the exact opposite of a traditional pharma company:
    • not broad-use drugs, but narrow-based
    • not closed, but open-source
    • not for-profit, but non-profit
  • an oncolytic virus is a weak virus that can’t takeover a healthy cell, but can takeover a cancerous cell (which is by definition weaker); the cancer cell then makes copies of the oncolytic virus, the cell dies, and the virus goes on to infect other cancer cells
  • the cost of synthetically printing DNA has been dropping dramatically
  • pharma is the opposite of Moore’s Law
    • me: what a16z jokingly calls eroom’s law (‘Moore’ spelled backward, because the costs of development have risen dramatically while # of approved drugs has fallen dramatically)

* * * * *

Robert Full: Secrets of movement, from geckos and roaches

  • animals have an array of secrets to move faster, better, up walls, etc
  • gecko feet literally act like tape, they peel onto and away from surfaces, this is intermolecular forces alone (unlike ants whose feet have some of the behavioral properties but use a type of biological glue)
  • other animals have tiny hooks on their feet, like cockroaches, to get more traction
  • still others use their legs to act like a second/supporting foot, for more traction
