Professor persona 2

I’m sick (and oh-so-very-tired) of this clueless, absent-minded, bumbling persona of mine. I’m sick of knowing nothing about the rw (that’s the real word), of always getting lost, of always forgetting stuff, of never having my cell phone around, of people patronizing me, of stupid little mistakes like today’s. It’s time to start paying attention, to notice my surroundings, to stop forgetting in the shower whether I already shampooed my head or not. I’m becoming (to some degree at least) a worldly person as of this moment. This is my official skin shed of the silly-clumsy-absent-minded-professor-persona. So long.

“Attention,” the articulate oboe was calling. “Attention.”

“Attention to what?” he asked, in the hope of eliciting a more enlightening answer than the one he had received from Mary Sarojini.

“To attention,” said Dr. MacPhail.

Of course I’m fascinated with the Speech Accent Archive: a massive (521 samples) archive of English accents from all over the world! They put native and non-native English speakers to read the same sound-rich English paragraph, record them, and then painstakingly transcribe the reading to phonetic symbols and even point out error generalizations (it turns out Mexican poblanos speak with “final obstruent devoicing”, “interdental fricative to stop”, and so on…). It’s pure beauty  —though it’s a shame that there’s only one Mexican accent in there, I’m thinking of sending my own recording (they do accept them and even have some precise instructions).

Being childfree myself —well, I’m somewhat young to claim that title for myself but that’s the lifestyle I want to live and I’ve already considered sterilization— it was a nice surprise to find The rise of the ‘childfree’ in Reddit’s1 homepage today. It was interesting to find out about Mariah, a Swedish girl who was sterilized at age 25; to read somewhere mainstream (The BBC) how much of a taboo the subject is; and to discover that there are actually groups lobbying for equality for people without children2 (Kidding Aside is the name of one!). That said, the article itself is quite irregular, too short, and too focused on women (though I may as well be reflecting my own biases).

And I don’t quite agree with most of the reasons put forth in the article (specially not with “I can’t believe the amount of waste that children produce.”). My personal reason for shunning child-rearing is that it is usually a cop-out to the existence question. It’s an usually unthinking way to give meaning to your life, to feel like you’ve “done something”, to achieve transcendence. I respect if you consciously want your children to give meaning to your life and you want them to be your life’s achievement —me, I’d like to explore different answers. (That said, life span is so long these days that one may try to juggle several answers that were of yore mutually exclusive.)

1 It’s interesting how snugly Reddit fits my demographics, some days ago they also had an article I found most interesting: ‘Grups’: Why do so many 40-year-olds still have 22-year-old lifestyles these days?.

Yey! A playlist serendipity has brought me back Roy Vedas’s wonderfully weird Fragments of Life (its weirdness is a fact). If I remember correctly it was Pako who first showed it to me, late nineties, and I hadn’t heard it in years (old, how past starts to pile up). Anyway, it’s definitely one of my favorite songs. Here, enjoy.

Society is a Neural Net 2

Neural nets are a popular technique in Artificial Intelligence based on simplified models of neurons and interneuronal connections gathered from brain research. Ray Kurzweil describes them pretty well here:

One basic approach to neural nets can be described as follows. Each point of a given input (for speech, each point represents two dimensions, one being frequency and the other time; for images, each point would be a pixel in a two-dimensional image) is randomly connected to the inputs of the first layer of simulated neurons. Every connection has an associated synaptic strength, which represents its importance and which is set at a random value. Each neuron adds up the signals coming into it. If the combined signal exceeds a particular threshold, the neuron fires and send a signal to its output connection; if the combined input signal does not exceed the threshold, the neuron does not fire, and its output is zero. The output of each neuron is randomly connected to the inputs of the neurons in the next layer. There are multiple layers (generally three or more), and the layers may be organized in a variety of configurations. For example, one layer may feed back to an earlier layer. At the top layer, the output of one or more neurons, also randomly selected, provides the answer.
The Singularity is Near, Ray Kurzweil

What hit me as I was reading this was how eerily close is society (as in human society) to a neural net. Think about it. Have you ever wondered how there are so many great and worthy causes being fought out there that you are not taking part of? You read, listen, think, and sometimes chat about them (you’re adding up the signals coming into you), but the signals simply do not exceed your (mostly random) threshold, and you don’t “fire”, you don’t act, your output is zero. (Street children and the EFF are the first examples that come to my mind, what are yours?)

Take me, for example: after many years of almost total political apathy, I’m close to releasing a web-app about Mexican Politics —in other words, I’ve become political (!)— because in the previous weeks several inputs conspired (somewhat randomly) to spur me into action. I’m an excited neuron in this weird, tragic brain that is Mexico and I only wish that I can get my next layer of neighboring neurons to fire.

Here’s a parting thought: media (and particularly ads) are the neurotransmitters of the hive mind.

The review itself is long and, though interesting at times, overall not that good, but there was a quiet, demure paragraph in it that kept me laughing the whole (did I say it was long?) review. Today I reread the paragraph in my notes and I’ve had a smile in my face ever since. This one’s a keeper:

A huge report was issued by the National Center for Health Statistics. It covered the topic of teenage oral sex more extensively than any previous study, and the news was devastating: A quarter of girls aged fifteen had engaged in it, and more than half aged seventeen. Obviously, there was no previous data to compare this with, but millions of suburban dads were quite adamant that they had been born too soon.

To someone who dropped out of college and has argued along this lines to defend his decision, who has been playing with online reputation systems for a while now, this comment by Alex3917 —originally posted here in response to Paul Graham’s newest essay— was an epiphany, tying and explaining it all together:

So lately I have been thinking a lot about “qualified experts,” as mentioned in the article. Credentialism became prominent in the 20s because of advances in transportation technology. Before WWI everyone lived in the same town their whole lives, so anyone could vouch for you. Then after WWI there was increased mobility, so no longer could your neighbors provide the credibility needed to get a job or get startup funding. Thus college stepped up to fill the role of the middleman. This was essential to keep society functioning, although certainly credentialism hasn’t done much for the learning aspect of college.

Today, however, we have the Internet. Everyone is linked to everyone and anyone can vouch for you. I can email the management of any company and assuming I follow basic email etiquette I can usually get a response. As digital identity improves, everyone will be able to vouch for you based on the information you are supplying about yourself online. For example, PG has his essays and one of his books on his personal website. Surely this is as meaningful as a college degree.

Also, college credentialism is a hierarchy because you have one person making value judgements about many people. Anyone who knows anything about network theory knows that networks are more powerful than hierarchies, because Metcalfe’s law trumps Sarnoff’s law. Thus college supplied credentialism is much less effective than what we are capable of reaching if we use the Internet. This is why many of the “qualified experts” are so imcompetent, because hierarchies are so much weaker than networks.

Anyway, if someone wants to make a sh*tload of money I’d suggest developing some tools for the Internet that start to fill the credentialist role that colleges play currently. The value there will make the 2 billion Facebook is trying to get seem like peanuts. :-)

Btw, have I told you about Schank’s Law already? I think not. Here it is in all it’s glory:

Schank’s Law

Because people understand by finding in their memories the closest possible match to what they are hearing and use that match as the basis of comprehension, any new idea will be treated as a variant of something the listener has already thought of or heard. Agreement with a new idea means a listener has already had a similar thought and well appreciates that the speaker has recognized his idea. Disagreement means the opposite. Really new ideas are incomprehensible. The good news is that for some people, failure to comprehend is the beginning of understanding. For most, of course, it is the beginning of dismissal.

by Roger Schank, as it appeared in The World Question Center 2004

What would you do if you realized you had become a 21 y.o. petulant, cranky, old fart1?

Golly! That’d be some positively nasty tidings2 —or not. Would you rather not know? There’s nothing left now but pick up the pieces, apologize, and start over.

1 I was on my way to becoming Melvin, from As Good As It Gets, wasn’t I? (Mel, btw, was so obviously a formist.)

Here’s an excellent formist intro to international auxiliary languagesWP written by Eward SapirWP himself (one of the most influential American linguists of the past century) in 1925:

There are many, many highlights to be made. Here’s four

  1. The “difficult and subjective concept” of the richness of a language, the “richness of connotations” (that phrase alone was worth the price of admission). This was precisely what I was getting at in my badly-received post On the Language of this Blog.
  2. “It is true that English is not as complex in its formal structure as is German or Latin, but this does not dispose of the matter. The fact that a beginner in English has not many paradigms to learn gives him a feeling of absence of difficulty, but he soon learns to his cost that this is only a feeling, that in sober fact the very absence of explicit guide-posts to structure leads him into all sorts of quandaries.. The simplicity of English in its formal aspect is.. really a pseudo-simplicity or a masked complexity.
  3. His dazzling insight that the problem of finding an adequate international auxiliary language is really the problem of how best to “symbolize thought.” Wow. Just wow.
  4. ”A common allegiance to a form of expression that is identified with no single national unit is likely to prove one of the most potent symbols of the freedom of the human spirit that the world has yet known.” ‘Nuff said.
* * *

Y’know, just between you and me, when the time is ripe—that is, in around 10 years—I would love to plunge myself in language: I would love to speak (and think in) Esperanto, Japanese, German, French, Mandarin, Portuguese, Italian, Catalan, Russian, Hebrew, Sweddish, Arab, Hindi… —Oh! Were languages not the harsh mistresses that they are! I’d love to work (and solve!) the problem of automatic machine translation (which, according to Kurzweil, will be the last task left for AI to emulate, the crucial last stepping stone to consciousness). I’d love to read both Ulysses and Finnegan’s Wake. I’d love to construct all sorts of constructed and auxiliary languages. I’d love to write in Esperanto and join la movado. I’d love to become a Wiktionary super-freak. I’d love to write language textbooks. I’d love to create a compiler and write programming languages. I’d love (in a most masochistic kind of way) to be a professional translator and translate a novel. I’d love to study some serious linguistics. I’d love to do advanced algebra. I’d love to become a Lisp super-freak or, quite oppositely, think in assembly code. I’d love to understand Goedel’s incompleteness theorem. I’d love to work in the semantic web. I’d love to create software to help one read and absorb written information (we have software to write, word processors, so why don’t we have software to read?).

Oh well, please excuse the future lapse.

I used to laugh at the elaborate calculations and stratospheric numbers you always find when reading papers about the limits of computation —as in, say, “Just how much computations per second might the entire universe theoretically support?”. It was something more than my incredulity (it involves too much hand-waving at times), it was simply indifference. So what if the universe could theoretically handle one zillion jillions to the gazillion cps? We might as well ponder how many angels might fit on the head of a pin…

I read Ray Kurzweil answer 3 weeks ago and it hasn’t stopped resounding on my head ever since:

Because computation underlies the foundations of everything we care about, from the economy to human intellect and creativity, we might well wonder: are there ultimate limits to the capacity of matter and energy to perform computation? If so, what are these limits, and how long will it take to reach them?

Our human intelligence is based on computational processes that we are learning to understand. We will ultimately multiply our intellectual powers by applying and extending the methods of human intelligence using the vastly greater capacity of nonbiological computation. So to consider the ultimate limits of computation is really to ask: what is the destiny of our civilization?
