Universal health care & AIG

The big problem with providing Canadian-style universal health care in the US is that it would basically nationalize a large part of the insurance industry (while also expanding it). Undeniably a huge disruption to a huge industry that employs many people. But now, the US government has, in effect, nationalised AIG", the biggest insurance company in the world. If the government ends up actually owning 80% of AIG, then why not use AIG to provide health insurance for the uninsured? Bang! Too good to be true, surely...

Subject: Re: Africa is giving nothing to anyone -- apart from AIDS

Dear Kevin Myers,

I agree wholeheartedly with your article.

Indeed, it is a melancholy object to those who walk through that
continent of Africa, when they see the streets, and "vast savanahs"
crowded with "sexualy hyperactive indigents" (as you so aptly put it),
importuning Europeans for aid every few years, generation after
generation. I agree with you that the prodigious number of children
they produce is, given the growing uncertainty of the global economy,
an unacceptable economic, environmental and aesthetic burden on the
lifestyles of the deserving people of the First World.

Ethiopia, as you point out is a particularly galling example. At 80M
population today, with a birth rate of  3-4% and a net population
growth of over 2%, the country is producing 1.6M new mouths to feed
per year. Of those, perhaps 100,000 have any chance of having a
lifestyle that you would consider decent. That leaves 1.5M useless
mouths to feed, 750,000 AIDS conveying organs of each gender, 3M
Kalashnikov wielding arms, etc.

At the same time, China and India are earning their place at the table
of the global economy, but in the process putting pressure on the
world's resources. In particular,  as has been well publicized, their
growing appetite for meat is driving up prices of meat, of soybeans
and corn further down the food chain, and even of oil and gas.

Having turned my thoughts for many years upon this important subject,
and maturely weighed the several schemes of other projectors, I have
always found them grossly mistaken in the computation.  The Gates
Foundation as you point out  is misguidedly deploying considerable
resources to make the problems worse by preventing malaria from doing
it's natural job. I would add that the US government, the United
Nations, the Global fund, and various and sundry funds dedicated to
enabling Africans with AIDS to continue spreading the disease are
tremendously counterproductive.

I shall now therefore humbly propose my own thoughts, which I hope
will not be liable to the least objection. I have been assured by very
knowing people of my acquaintance that a young healthy child well
nursed is at a year old a most delicious, nourishing, and wholesome
food, whether stewed, roasted, baked, or fried; and I make no doubt
that it will equally serve in a lo mein or a curry with rice.

I do therefore humbly offer it to your consideration that of the
previously computed 1.5M excess Ethiopians produced annually, 150,000
be kept for breeding, and the remaining 1.35M,  at a year old, be
offered in the sale to reputable global agribusiness corporations;
always advising the mother to let them suck plentifully in the last
month, so as to render them plump and fat for a good table. This
supply of about 15,000 metric tonnes per year of additional
high-protein food will, if appropriately marketed to the growing
markets of Asia, relieve global prices of a wide range of connected
commodities by up to 10%. Your average countryman stands to save at
least 100 Euros per year in gasoline alone!

I think the advantages by the proposal which I have made are obvious
and many, as well as of the highest importance. The risk of AIDS
bearing immigrants will be reduced, the reduction in civil wars in
Africa will free up more television time for entertainment in the
First World,  increasing not only viewing pleasure but also
advertising revenues and thus commerce and overall economic
well-being, and of course, the long-suffering consciences of the West,
rather than needing to be relieved by constant doses of aid-giving,
will be fully cured of  that most senseless and nagging feeling of
guilt. Many other advantages might be enumerated.

I profess, in the sincerity of my heart, that I have not the least
personal interest in endeavoring to promote this necessary work,
having no other motive than the public good of the deserving First
World, by advancing its trade, providing food for its growing
partners, and relieving its citizens. Though I am Ethiopian myself, I
have no children by which I can propose to get a single penny.

Sincerely,

Yonatan Fetanu

Electoral markets

In my last entry about prediction markets vs polls, I quoted and linked to some aggregate numbers from Intrade for the US presidential election. Now there's Electoral markets, a website called that displays the prediction markets at the state level. Cool stuff! I came across it in a blog entry that sums it up quite well.

A ride-by demographic study, one subway car:

Apophis & carpe diem & how to save the world with a billion keychains

There's a 0.0023% chance that asteroid Apophis will impact earth in 28 years. Who cares about a 1 in 45,000 chance? Believe it or not, it is useful information.

For example, you could use this information when negotiating a 30-year loan -- structure it so payments are more heavily weighted to the last two years! At what cost? Of course the world won't end, but if there's a chance... you can precisely calibrate your degree of carpe diem. You should be willing to pay up to $1 for every extra $45,000 (plus additional interest) that is deferred to the last two years. Many people spend $1 on a lottery ticket where you have a 1 in 689,065 chance of winning $10,000. And of course a big loan with a small chance you won't have to pay it back is the same as a lottery ticket -- in fact even better since a) this one pays upfront and b) the normal lottery ticket is overpriced by an order of magnitude.

Back to Apophis. Here's another, less selfish, example of how this information can be useful. We want to know how much money it makes sense for us (earth, one world united!) to spend defending against Apophis. The answer is 0.0023% times the present value of world GDP, cumulated from 2036 forward. Oops that's infinity... Wait not necessarily. If we assume GDP stops growing at some point (e.g. the point where all material needs of humanity would be easily met), and we assume a a discount rate strictly greater than zero, the present value of all future GDP is a finite number. So we should multiply that number by 0.0023% and invest it in a laser beam.

Laser beam schematic:



Take that, make it a billion times more powerful, with a nuclear battery, put it in a satellite with some stuff for aiming and we should be ok! Seriously though, we do have 28 years to work on the technology, so no biggie. But how do we create the political will to spend money on it now?

Societies seem to have a hard time making really long-term investments, whether they are democracies or whatever. But they all love lotteries! Let's revisit the deferment of debt idea. The borrower will be willing to pay a premium to take some debt and push it back past the 28th year. The lender is neutral since they get extra fees to compensate for the risk. Thus we have an efficient transaction between a rational borrower and a rational lender. OK and what has that got to do with asteroids? Recall this is essentially a lottery, one that's better than the usual ones, and we know people are willing to pay 10 times the rational price for lottery tickets. Therefore it should be possible to satisfy the lender with just 1/10th of the fee collected from the buyer! And the remaining 9/10th can be used to build a giant laser beam!!! Everyone's happy. In fact, since the beam also works to eliminate or reduce that very risk, the rational lender might even be willing to contribute part of their one tenth. And then everyone's even more happy. Let's call this the GAALBMF: global anti-asteroid laser beam mortgage fund.

Karma Tycoon

Due to a recent ahem... incident, I stumbled across some old press coverage for Karma Tycoon. Cool! Not just because it's a fun and educational game which anyone can play free (check out the the rave reviews), but because yours truly wrote the game server.

It was a one-off contract for Do Something. 9mmedia, developed the client-side and outsourced the server-side to me at IHN, back in 2006 when IHN needed some cash. It ended up being a pretty cool project... 9mmedia guys are great to work with. I highly recommend them.

The game was fun and interesting to design and implement (but not the schedule -- that was rough especially since I was also busy with some other stuff). We used red5 to interface between the java server and flash client. I was also able to use some components of Merkato too, which was nice.

Mars Landing

'Phoenix Mars Mission scheduled to land May 25, 2008, is the first in NASA's "Scout Program." Scouts are designed to be highly innovative and relatively low-cost complements to major missions being planned as part of the agency's Mars Exploration Program.'

Canary in a coal mine

pulse, naymz, doostang, fastpitch, ...

That is the list of new social networks I've received invitations to join just recently. Some are new, some are old websites recylcing themselves as social networks. Before that, there was ning, facebook, linkedin, geni.com, myspace, friendster, hi5... This is crazy. Have we reached the boo.com stage of facial neworking? (Oops. I just realized I wrote facial instead of social. That's hilarious).

Meanwhile, Blog Friends -- the one thing that I found most promising on Facebook (at least as an example of a feature that I could make use of, not necessarily a general killer app that would change the world) -- died an ominous death. Ominous for Facebook that is. But in it's last gasp, it inspired a useful cliche. The day it died, my status message: wondering if Blog Friends was like a canary in a coal mine.

Why that analogy? See what Blog Friends themselves said: "... we have been at the mercy of Facebook's frequent modifications of their Platform specifications, and that has also been another disabling factor for us." So I remain firmly in the camp of Facebook skeptics -- at best, it's the next AOL (which is still huge).

I remain however a huge fan of Geni.com. That one that should be good for generations.. literally.

Overall, I hope social networking becomes something that's not quite a separate app, and not just a feature, but a service/capability as ubiquitous, useful and unobtrusive as ... email! (Hey check that out: 3 "U"s! Now I sound like a cheesy business book). Somebody should create standard api and ... yeah! Something called Open Social... That would be pretty promising!

Of course, I've been wrong before on this kind of stuff.

Predictions, elections, polls, fractals, reflixivity & the kitchen sink

People argue about whether prediction markets do a better job of forecasting elections than polls, or it's an illusion due to timing.

Initially, I am inclined to believe this is one area where the market works better. This follows from their most basic properties. Let's assume both are mostly mediocre. That is many polls and prediction markets available, but just no good in general.

Now consider polls. If there was fewer of them, and they were well communicated, we could count on the fact that expert from all sides would scrutinize them and that they would thus be held to the highest standards. Or of course if you average a lot of polls, you should get a more accurate poll of polls, as errors cancel out. In both cases, centralization increases accuracy of polls. Conversely, when looking at any one poll alone chances are, the one you're looking at is a bad/biased one.

For markets on the other hand, even if you are looking at one market alone, if it was biased, all it would take is one person who has seen the other markets to arbitrage the bias away, in effect linking the two markets and making them two views of one more accurate underlying market. Two polls cannot get organically linked and become more accurate than each by itself. You have to add them up yourself. But two markets can! Thus any one market you stumble upon is more likely to be accurate than a poll you stumble across.

This argument seems particularly apt for the US presidential elections, since there's so much slicing and dicing... The polls are all complicated what-if scenarios. So anyway, according to Intrade, which I've written about before, here are the current probabilities for the next US President (taking bid prices, to get lower bounds):

• Obama: 55.6%
• McCain: 37.6%
• Clinton: 6.6%

And the Iowa Electronic Markets seem to agree. Thus, the above, in my humble opinion, is as close as you're gonna get to a prediction out there today.

But is it any good?

Getting back to the philosophical argument again... polls are trying to measure current feelings, i.e. they assume there's an underlying "true" preference of the public, and that they are an objective mechanism to reveal it, within a certain Gaussian error. But it could of course be that the error is much larger than we think possible, because the models are completely wrong. As Nassim Nicholas Taleb, the author of Black Swan, that I mentioned here a couple of posts ago, has argued, a lot of mistakes are due to imposing Gaussian models on a reality that has fractal or power-law or heavy-tailed scaling. For polls, if you think there is a true current preference, then I guess the error should be Gaussian (in other words, using Taleb's lingo, the preference is "in mediocristan"). But looking at it over time, as you must for a prediction, maybe a single poll of a few thousand people, even if it's not representing a wider reality, can have a fractal effect, replicating it's belief patterns at larger scales, through media. If that' s the case, most polls will be meaningless, some will be virally important. And prediction markets won't work well either. True the participants size can scale so maybe they can make fractal bets, but no matter how many expert bets the market brings in, it won't improve the information about a black swan type event which is what a fractally scaling popularity would be.

Some people, like George Soros in his recent book (that I just picked up this weekend) argue that, when it comes to human/social phenomena, the underlying reality doesn't exist separately, it is entangled with human attempts to understand it, and manipulate it (he calls it reflexivity). So taking his ideas to polls, are they measuring something that fundamentally may not actually exist? Probably, there's no objective public opinion that exists independently, waiting to be measured. But it exists reflexively (this is my interpretation/application of Soros idea here so sorry if it's wrong). The polls, even if totally arbitrary to start with, by being communicated, may induce the reality they purport to measure. People listen to the news, and the polls, and their future actions are affected in some way, may then come to act in the way that is suggested to them by the polls for people like them. It may or may not be controlled in concentrated way, but if we apply this theory, then polls are as much instruments of action as measurements, in robotic terms, as much actuators as sensors.

Drexler redux: nanotech

Blog: noun, abbrev. Etymology: Web log.

A year ago, I logged a note to revisit Hanson & Drexler. One day, I was at The Strand, actually remembered and ended up picking up K. Eric Drexler's Engines of Creation (I now see there's a new edition that's even available as an e-book, but I didn't know that at the time, and just got the original edition). Incidentally, that event proves this blog is serving it's purpose! If it wasn't for this blog, my faint connection to that book might have gradually faded into the past. I also picked up Black Swan, which I ended up really enjoying but I digress...

Engines of Creation is pretty cool. First surprise: It is perhaps the seminal work in Nanotechnology. In fact, Drexler coined the term. I didn't know that. I found Drexler interesting because of a paper he wrote with Bernardo Huberman on agent/market-based computing systems. But it turns out he is the Godfather of nanotechnology. Wow indeed. Second observation: considering it's a book about future technology published in 1986, just the fact that I was able to read most of it says a lot. Usually non-fiction books about future technology don't age well: either they were right and so what they contain is now obvious, or they were wrong and are now useless, except for a few predictions that live on as comedy. But not this one. It is still absolutely readable. It does waste a bit too many words on appeasing fears of doomsday scenarios, and has a bit too much juvenile moralization. Just a bit. But the 2/3rds or so that I did read closely was fascinating stuff which hasn't aged a bit. It's great, the first time I got some clue about how nanotechnology might work.

Indeed, I had always had a hard time bridging the gap between the fictional nanotech that I found so brilliant in Diamond Age by Neal Stephenson, and anything I knew about science or technology. Not surprising since it's sci-fi, you might say, but my point is that "nanotech" exists in real science yet I don't see no microscopic helicopters and infinite-dimensional interactive books being talked about in the newspaper. What you hear about is relatively mundane "nanotech" ideas. Relatively of course, because by normal standards, even "boring" nanotech's promises are huge ... Microscopic "hard disks", or carbon nanotubes that conduct electricity much better than wires, or can support structures that are impossible with steel like space elevators!

But the Drexler vision is much bigger than better construction materials. He imagines actual nano-machines that build stuff, actual mechanical assembly of atoms and molecules. If you accept that premise, it leads to gigantic consequences, essentially limitless food, energy, all our material needs becoming ... immaterial, so to speak. This is a big idea. And it turns out Mr Drexler has made it the work of his life.

Which brings us to the question... So how come his book is not obsolete? After twenty years f being the breakthrough birth of a new field, why are those ideas still not well known to the general public, when the buzzword they created seems to now mean something much less. Well it turns out Wired magazine has answered this question in a 2004 article on K. Eric Drexler entitled "The Incredible Shrinking Man". You can read the details in the article, but in short there's a great ideological divide in nanotech, and it looks like the "incrementalists" who focus on new nano-materials and so on won the research politics battles over Drexler who wants to build nano-machines.

Now I feel for Drexler in a different way. Not just as a fascinating guy who I should follow-up on but as a human story too. Could he be like Edwin Armstrong, who invented FM radio and many other great things, but lost all the crucial battles in his life? Or is it going to be a classic story of early brilliance, fall from grace, long struggle, and ultimate righteous triumph... Hmm I think that's classic but I can't think of any examples right now. Anyway here's a possible triumphant ending: nanobots win the prize for removing carbon from the atmosphere. Imagine a little machine made of a few atoms of X that uses solar power to move around and grab CO2 from the air, and then attaches the C to some part of itself, releases the O2, and then falls to earth as XC dust. It could even be called something cool, like photosynthesis.. haha. Who knows, if X is right, that XC might even be a source of fuel! So in the end, our hero stops global warming and saves the world! Good night kids.
