The Probability of Future

What is in store for us in the future? This has always been an intriguing question. 

Future, for us, if often vast and uncertain.

Future - Vast and Uncertain

I came across this interesting note while reading some of the forums about the mysterious disapperance of MH370, the Malaysian Airlines Flight from Kuala Lumpur, Malaysia to Beijing, China.

The flight started around 12:41 AM Malaysian Time on 8th March 2014, onwards to Beijing. Somewhere around an hour past the take off, the flight lost control with the ATC and disappeared off the civilian radar. As on 9th March 2014, the whereabouts of the flight , and its 229 passengers and crew, was unknown.

This is when I read the note. The note goes as below.

Like many biological variables, life expectancy is from Mediocristan, that is, it is subjected to mild randomness.  It is not scalable, since the older we get, the less likely we are to live.  In a developed country a newborn female is expected to die at around 79, according to insurance tables.  When she reaches her 79th birthday, her life expectancy, assuming that she is in typical health, is another 10 years.  At the age of 90, she should have another 4.7 years to go.  At the age of 100, 2.5 years.  At the age of 119, if she miraculously lives that long, she should have about nine months left.  As she lives beyond the expected date of death, the number of additional years to go decreases.  This illustrates the major property of random variables related to the bell curve.  The conditional expectation of additional life drops as a person gets older.

With human projects and ventures we have another story.  These are often scalable...With scalable variables, the ones from Extremistan, you will witness the exact opposite effect.  Let's say a project is expected to terminate in 79 days, the same expectation in days as the newborn female has in years.  On the 79th day, if the project is not finished, it will be expected to take another 25 days to complete.  But on the 90th day, if the project is still not completed, it should have about 58 days to go.  On the 100th, it should have 89 days to go.  On the 119th, it should have an extra 149 days.  On day 600, if the project is not done, you will be expected to need an extra 1,590 days.  As you see, the longer you wait, the longer you will be expected to wait.

Let's say you are a refugee waiting for the return to your homeland.  Each day that passes you are getting farther from, not closer to, the day of triumphal return.  The same applies to the completion date of your next opera house.  If it was expected to take two years, and three years later you are asking questions, do not expect the project to be completed any time soon.  If wars last on average six months, and your conflict has been going on for two years, expect another few years of problems.

Interesting thought, isn't it?

Regarding the flight in question, today, a week later, the flight is still untraceable. Theories are abound about its disappearance, right from a hijack, pilot suicide, mechanical error et al. 

I wish and hope, the flight, and its PAX and crew are found safe and sound.
