So here’s an argument against irreducible complexity. Take a family that works hard for a living, saves a large chunk of its earnings for old age, emergencies, sending kids through college, and so on. Then create (through some combination of amino acids and other proteins) an institute that offers insurance against disaster. The family, being prudent, realizes that the insurance, while it costs them a little more each month, could potentially save them thousands of dollars in the long run, and so it buys into the insurance company. Now introduce a mutation: the family decides that since disasters are covered, they can divert a little more money into luxuries. Repeat this process with a health care institute that helps cover the soaring prices of medication; a loan agency to cover college tuition (which is steadily outpacing what the normal family can afford); a loan agency to cover the cost of a business; a house; a car; anything at all with the swipe of a plastic card with a magnetic strip. With that final mutation, we now have a system in which the removal one component causes the whole organism to fail, and yet was built up by increments.
Nearly half a year after the great crash that marked our current recession as one of the worst in decades, we are still bleeding. Our economy continues to shed jobs; the stock market wavers, falls, stabilizes, wavers, and falls again; big businesses, like the insurance titan AIG, continue to need billions of dollars of bailout money just to survive; and the government continues to scramble to pass legislation that supposedly will fix all our problems, but in reality will simply make matters worse. The gigantic stimulus package was laughable (in more a mad, gibbering, hysterical laughter than a ha-ha laughter) in that hundreds of pet projects suddenly found funding, but precious little in the bill actually targeted economic stimulus, and much of the spending won’t happen immediately.
