Man and Supermouse

More speculations by Yuval Noah Harari. He thinks H. sapiens has only a few decades left.

Flowers for Algernon, written by Daniel Keyes in 1958, was one of the most successful Science Fiction short stories (later, a novel, play and film) of all time. It starts with the title mouse getting a dramatic IQ upgrade. Fifty-five years down the pike, it seems that science has caught up with the fiction. The genius mouse has been engineered.

One might think that Harari's judgement on our limited future means he is a technological pessimist. This is hardly the case. He doesn't think we are likely to annihilate ourselves. Instead, he thinks it is likely that we will transform ourselves. The genomes of fish and potatoes are being merged to create frost resistant potatoes. Potential artificial organs for humans are being grafted onto mice.

One of the most prescient science fiction writers of my childhood was Arthur C. Clark, who in addition to envisioning communications satellites and smart phones, wrote Childhood's End, an SF novel on the theme of mankind transformed.

Bioengineering is not a new wrench in the human toolbox. Thousands of years ago we were castrating bulls to make more docile oxen, and men to make eunuchs. Grafting a fruiting branch onto a hardier root stock is of similar antiquity. What is new is the power of genetic engineering. The same tools which created the modern day Algernon are being developed at extraordinary speed. The principal obstacles to human application, says Harari, are mainly ethical and legal. It seems likely that at some point crucial breakthroughs will bring benefits too large to be resisted - perhaps some transplants that will defeat Alzheimer's - and I think such experiments are already underway. Would, or should, parents resist genetic modifications to make their children smarter, prettier, happier, or more disease resistant?

Thirty thousand years ago one of our possible ancestors made an ivory figurine of a man with a lion's head. The sorts of things they imagined, and much better and stranger things, are increasingly within our potential grasp. Would it be a bad thing if our descendants were not just randomly assorted genetic copies of ourselves but smarter, healthier, less violence prone, and longer lived - a veritable new species?

Anti-Libertarian: re-post

The most pointed critique of social security and liberalism in general is the libertarian critique. The problem with libertarians, for a liberal, is that we have too much in common. We both believe in individual rights, tolerance of individual differences, and dislike government prescription of religion. The basic difference, it seems to me, is the different answers we give to Cain's (with thanks to the Captain - my original version had the corpse asking the question!) famous question: "Am I my brother's keeper?" That's not really my basic bitch against the libertarians though. My real complaint is the same as my complaint against most religion - its premise is a fraud. For those who can't stand to wait for the punchline, I believe that trying to implement libertarian principles leads to tyranny or social disintegration. Demonstrating that takes some historical (and pre-historical) context. For all but the last 15,000 or so of the 100,000 years the human spec

Uneasy Lies The Head

Uneasy lies the head that wears a crown ........... Shakespeare Henry IV, Part II. So it is with us and our slightly distant primate cousins , so it seems. A 9-year study of wild baboons in Kenya by Princeton University and the Institute of Primate Research may turn conventional assumptions of alphas males upside down. The study found that alpha males have high testosterone levels, which allows them to dominate other baboons, get access to more food, and attract better mates. This is expected. Surprisingly, though, the alpha males also have high levels of stress hormone glucocorticoid, which scientists measured from their feces samples. In fact, the stress of alpha baboons was on par with low-ranking baboons. The convention wisdom is that access to food and females provides life security and thus less stress for dominant males. Conversely, weak males who are constantly threatened by starvation and physical violence from stronger males are thought to be more stressed. The st

We Call it Soccer

The US played its best, and maybe only good game of World Cup, but lost thanks to brilliant goalkeeping by the Swedish keeper and the bizarre method soccer uses to settle ties when three US stars could not put the ball on frame from the 12 yard spot.  At the end it came down to a blocked shot that spun in by maybe a couple of centimeters. Well, that's football - too much like life.   Which brings me to a modest proposal.  Replace the thirty minute overtimes with as many 7-player 15 minute periods as needed to settle it.  Scoring should be much easier with fewer players.
