Mathematics in Chalk A photography project reveals the allure of equations in mathematicians’ blackboard work /21-04-22

g-2 The new measurement from the Muon g-2 experiment at Fermilab strongly agrees with the value found at Brookhaven and diverges from theory with the most precise measurement to date.
 …  muon is sensitive to something that is not in our best theory
 …  g-factor: 2.00233184122(82)
 …  at a significance of 4.2 sigma /21-04-18

Our New Robot Overlords
 …  Boston Dynamics
 …  the result was always the same: Uncontrollable machine self-improvement would one day overcome humanity.
 …  We would be lucky to be domesticated as pets
 …  The robots are now humanity’s saviors, suppressing bad human mass behavior online with increasingly sophisticated filtering algorithms.
 …  an AI system that induces tumours in every human to quickly find an optimal cure for cancer, and a geoengineering robot that asphyxiates humanity to deacidify the oceans
 …  technological “singularity” .. intelligence of some machine agent, or a collection of them, suddenly increases exponentially
 …  Maciej Cegłowski
 …  automated systems might prove catastrophic. The promised solution (simple enough!) was to rectify human desire. But once we lost optimism about whether this was possible
 …  the only way to win is not to play at all
 …  Wiener
 …  If what we consciously want is different from what we unconsciously want, which of these do our actions reflect?
 …  We may believe that we are the origin of our thoughts and actions, but we may instead obey unconscious instinct, sophisticated psychological patterns configured through evolutionary processes, or the inescapable influence of our peers and the societies we live in.
 …  machines fight against the memes — ironically, for the people who devoted themselves to controlling the machines unwittingly invited them to control us. /21-04-07

Computers Why Computers Won’t Make Themselves Smarter. We fear and yearn for “the singularity.” But it will probably never come.
 …  St. Anselm .. God is, by definition, the greatest being that we can imagine; a God that doesn’t exist is clearly not as great as a God that does exist; ergo, God must exist.
 …  God isn’t the only being that people have tried to argue into existence.
 …  Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever .. Irving John Good .. 1965
 …  recursive self-improvement
 …  I.Q. of 350 into a person with an I.Q. of 400. And so forth.
 …  Emerson Pugh .. “If the human brain were so simple that we could understand it, we would be so simple that we couldn’t.”
 …  C. elegans .. mapped every connection between its three hundred and two neurons. But they still don’t completely understand its behavior. The human brain is estimated to have eighty-six billion neurons on average, and we will probably need most of them to comprehend what’s going on in C. elegans’s three hundred and two; this ratio doesn’t bode well for our prospects of understanding what’s going on within ourselves.
 …  once we create software that is as intelligent as a human being, running the software on a faster computer will effectively create superhuman intelligence.
 …  Creating a smarter A.I. requires more than the ability to write good code
 …  The technique of having a compiler compile itself is known as bootstrapping, and it’s been employed since the nineteen-sixties.
 …  Human programmers sometimes hand-optimize sections of a program, meaning that they specify the machine instructions directly; the humans can write machine code that’s more efficient than what a compiler generates, because they know more about what the program is supposed to do than the compiler does.
 …  To what extent can you simultaneously optimize a system for every possible situation, including situations never encountered before?
 …  intelligence explosion implies that there is essentially no limit to the extent of optimization
 …  this is different from individual intelligence
 …  self-improvement takes place—not at the level of individuals but at the level of human civilization as a whole
 …  a lot of people drawing inspiration from one another
 …  DNA as an example. James Watson and Francis Crick were both active for decades after publishing .. but none .. were made by them .. someone else did
 …  the same way that we needn’t worry about a superhumanly intelligent A.I. destroying civilization, we shouldn’t look forward to a superhumanly intelligent A.I. saving us in spite of ourselves. For better or worse, the fate of our species will depend on human decision-making. /21-04-04
