The DART

The space administration's plans to throw a refrigerator at an incoming small asteroid (1) to demonstrate fancifully worded, "kinetic impactor technique," is ample proof that humans are sitting ducks on the blue planet surrounded by big and fast objects. Momentum has been known for a while and if one can impact the direction of the approaching object slightly, it could be beneficial. But to be effective, such a maneuver has to be very early in the trajectory of the approaching object. Combined with a lack of knowledge of projectiles moving toward us, it remains to be a probability game - and the odds are likely against the species, still trying to kill each other around the world.


If the state of the art is studying the effect of an impact of a heavy projectile on an approaching asteroid, it seems that we have not advanced sufficiently to survive. If the best minds in practical space exploration are engaged in tactics, we may be in more terrible shape than could be imagined. Aided by policy making ignoramuses in the capitol, trying to cut funding for fundamental research, we now have a stagnant knowledge regime, unable to advance science and humanity. To make matters worse, we have engineers and technologists focused on applying old ideas just to win funding. 


Stupidity has a price. In most past failed experiments in civilizations, it ended up with an ignorant leader perpetuating tactics surrounded by those currying for favor by applying old ideas to solve new problems.

The quantum phone call



Ever since the phenomenon of entanglement was discovered, humans have been enthralled by visions of communication at faster than the speed of light. Recent experiments with the Micius satellite (1) appear to move us closer to practical satellite based quantum communication. Bringing entanglement to applications could propel humanity to a different level.


Humans have been constrained optimizers. From inception, they have been prisoners of space and time. Their ability to physically transport their inelegant bodies has been inferior to most animals that surround them and their inability to see for half the day, made them vulnerable. Later, they will find that they cannot communicate faster than the speed of light and they cannot travel faster than a fraction of this theoretical limit. To make matters worse, they were greeted by silence in close quarters, albeit their space broadcasting and listening methods, remain embarrassingly archaic. Humans remain to be prisoners of space and time and it appears that it would be forever.


Entanglement provides a mild hope out of these hard constraints. Beating light can lift the spirits of humans and open up the universe that largely remains unapproachable.

The autoimmune era

Humans, it appears, have successfully conquered external biological threats to them, at least in the short run. One implication of this dominance is the alarming rise of autoimmune diseases that now account for most of the healthcare costs. Their finely tuned and powerful immune system has become a great liability for the modern humans, devoid of bugs. Boredom of overdesigned systems appear to be as deadly as anything else. Recent discovery of rare diseases in which the immune system attacks the brain itself is a constant reminder that the biggest threat for humans in the long run is their own immune systems.
 
Heart disease, cancer, mental disorders, COPD, asthma, arthritis, diabetes and hypertension account for over 80% of the healthcare costs. The bugs are not implicated in any and it appears that the body has begun to attack itself. Original design deficiencies in Homo sapiens have certainly caught up with them. The plumbing was never designed to last more than a few decades and the body, now stretched to twice the original design life, seems to struggle to get rid of the waste products both in the brain and in the circulation systems. To make matters worse, humans invented agriculture recently and this has fundamentally changed the course of their health. They have been feeding themselves material that neither the body nor the bacteria in their guts have ever been designed to efficiently digest.
 
We are in the autoimmune era, in which most humans will die because of the efficiency of their immune systems or the inability of the circulations systems to discharge waste products. Medicine and Engineering are certainly converging, but not in a way that technologists imagined.
