Theory of Self-Reproducing Automata - John von Neumann

Comparisons between computing machines and the nervous systems. Estimates of size for computing machines, present and near future.

Estimates for size for the human central nervous system. Excursus about the “mixed” character of living organisms. Analog and digital elements. Observations about the “mixed” character of all componentry, artificial as well as natural. Interpretation of the position to be taken with respect to these.

Evaluation of the discrepancy in size between artificial and natural automata. Interpretation of this discrepancy in terms of physical factors. Nature of the materials used.

The probability of the presence of other intellectual factors. The role of complication and the theoretical penetration that it requires.

Questions of reliability and errors reconsidered. Probability of individual errors and length of procedure. Typical lengths of procedure for computing machines and for living organisms--that is, for artificial and for natural automata. Upper limits on acceptable probability of error in individual operations. Compensation by checking and self-correcting features.

Differences of principle in the way in which errors are dealt with in artificial and in natural automata. The “single error” principle in artificial automata. Crudeness of our approach in this case, due to the lack of adequate theory. More sophisticated treatment of this problem in natural automata: The role of the autonomy of parts. Connections between this autonomy and evolution.

- machines faster: 5 ms from neuron potential to neuron potential, 10^-3 ms for vacuum tubes

Charade | West Hunter
I was watching Charade the other day, not for the first time, and was noticing that the action scenes with Cary Grant (human fly, and fighting George Kennedy) really weren’t very convincing.  Age. But think what it would be like today: we’d see Audrey Hepburn kicking the living shit out of Kennedy, probably cutting his throat with his own claw – while still being utterly adorable.

Was thinking about how there are far too many reviewers, and far too few movies worth reviewing. It might be fun to review the movies that should have been made, instead. Someone ought to make a movie about the life of Konstantin Rokossovsky – an officer arrested and tortured by Stalin (ended up with denailed fingers and steel teeth) who became one of the top Soviet generals. The story would be focused on his command of 16th Army in the final defense of Moscow – an army group composed entirely of penal battalions. The Legion of the Damned.

There hasn’t been a good Gulag Archipelago movie, has there?

One historical movie that I’d really like to see would be about the defense of Malta by the Knights of St. John. That or the defense of Vienna. Either one would be very “timely”, which is a word many reviewers seem to misuse quite laughably these days.
My oldest son made the same suggestion – The Great Siege

Siege of Vienna – Drawing of the Dark?

The Conquest of New Spain.
Only Cortez was fully awake. Him and von Neumann.

Interview Greg Cochran by Future Strategist

- IQ enhancement (somewhat apprehensive, wonder why?)
- ~20 years to CRISPR enhancement (very ballpark)
- cloning as an alternative strategy
- environmental effects on IQ, what matters (iodine, getting hit in the head), what doesn't (schools, etc.), and toss-ups (childhood/embryonic near-starvation, disease besides direct CNS-affecting ones [!])
- malnutrition did cause more schizophrenia in Netherlands (WW2) and China (Great Leap Forward) though
- story about New Mexico schools and his children (mostly grad students in physics now)
- clever sillies, weird geniuses, and clueless elites
- life-extension and accidents, half-life ~ a few hundred years for a typical American
- Pinker on Harvard faculty adoptions (always Chinese girls)
- parabiosis, organ harvesting
- Chicago economics talk
- Catholic Church, cousin marriage, and the rise of the West
- Gregory Clark and Farewell to Alms
- retinoblastoma cancer, mutational load, and how to deal w/ it ("something will turn up")
- Tularemia and Stalingrad (ex-Soviet scientist literally mentioned his father doing it)
- germ warfare, nuclear weapons, and testing each
- poison gas, Haber, nerve gas, terrorists, Japan, Syria, and Turkey
- nukes at https://en.wikipedia.org/wiki/Incirlik_Air_Base
- IQ of ancient Greeks
- history of China and the Mongols, cloning Genghis Khan
- Alexander the Great vs. Napoleon, Russian army being late for meetup w/ Austrians
- the reason why to go into Iraq: to find and clone Genghis Khan!
- efficacy of torture
- monogamy, polygamy, and infidelity, the Aboriginal system (reverse aging wives)
- education and twin studies
- errors: passing white, female infanticide, interdisciplinary social science/economic imperialism, the slavery and salt story
- Jewish optimism about environmental interventions, Rabbi didn't want people to know, Israelis don't want people to know about group differences between Ashkenazim and other groups in Israel
- NASA spewing crap on extraterrestrial life (eg, thermodynamic gradient too weak for life in oceans of ice moons)

Information Processing: Machine Dreams
This is a controversial book because it demolishes not just the conventional history of the discipline, but its foundational assumptions. For example, once you start thinking about the information processing requirements that each agent (or even the entire system) must satisfy to find the optimal neoclassical equilibrium points, you realize the task is impossible. In fact, in some cases it has been rigorously shown to be beyond the capability of any universal Turing machine. Certainly, it seems beyond the plausible capabilities of a primitive species like homo sapiens. Once this bounded rationality (see also here) is taken into account, the whole notion of optimality of market equilibrium becomes far-fetched and speculative. It cannot be justified in any formal sense, and therefore cries out for experimental justification, which is not to be found.

I like this quote: This polymath who prognosticated that "science and technology would shift from a past emphasis on subjects of motion, force and energy to a future emphasis on subjects of communications, organization, programming and control," was spot on the money.

[1501.03988] A One-Dimensional Physically Universal Cellular Automaton
Physical universality of a cellular automaton was defined by Janzing in 2010 as the ability to implement an arbitrary transformation of spatial patterns. In 2014, Schaeffer gave a construction of a two-dimensional physically universal cellular automaton. We construct a one-dimensional version of the automaton.
