Wasting resources

A recent article in Child Development shows what has been obvious to many – stressful home environments have significant deleterious effects on a child’s development. Since such low level stress is generally negatively correlated with income and wealth, children from the lower economic strata are at a much higher risk of this phenomenon. As the technologists and politicians strive to build a “better society,” they are completely ignorant of the most important resources, being wasted – children.

As more than one third of the world’s children, impacted by lack of food, shelter and education, struggle to make sense of a system that seems to be moving backwards with lack of empathy and knowledge, we are fast approaching a stalemate. The intelligentsia, appear to understand the mechanics of Net Present Value (NPV) for their pet projects, but often miss applications of finance and economics for policy that may positively impact society. Even the Nobel Laureates from the “Chicago School,” famous for seeing beyond the mountains, seem to have lost the desire to make a fundamental change. Tacticians galore and in the process, we are losing.

Any policy, that does not have a positive impact on malnourished, undereducated and stressed children, occupants of this planet tomorrow, is not worth pursuing.

Societal memory

Recent finding that amnestic mouse brains are able to recall lost memories is encouraging for those with Traumatic Brain Injury and Alzheimer’s disease related memory loss. Lost memories, perhaps, the most costly aspect of human societies, have not been studied in sufficient detail. For most of the history of homo-sapiens, downloading memories was central to their development – with the village elder willingly transmitting knowledge to the chosen few of the next generation for perpetual propagation. Modern humans, virtual slaves to technology, seem to have lost the art of memory storage and propagation, yielding to the least effective mechanism for the same, computers.

Memories, that encapsulate experience and knowledge, are misunderstood by humans on a treadmill to nowhere. The rat race keep them occupied for most of their lives, unable to make memories or to appreciate those who create them. A society that is unable to store and propagate memories is not sustainable, for its content will be left undefined and its tactical accomplishments, fleeting. A human, the combined total of chemicals worth less than $25, is nearly worthless without memories – her own, or those of her society. In spite of all their technical accomplishments, humans will drift endlessly if they could not figure out how to create, nourish, store and utilize societal memories.

Memories – most valuable but least understood resource of a society – may ultimately define the path humans could take.

Inelegant science

Science, perhaps the only accomplishment of modern humans, is affected by the collective myopia of scientists – the tendency to spend too much time on details and little on larger questions. For example, recent revelations that indicate that the universe is so finely tuned to be flat that even an addition of a single gram of mass into the system could substantially change its future, seem to have gotten little attention. Attempted descriptions of dark matter, energy, flow and tilt – with heavy and incomprehensible mathematics is the status-quo. Some at space agencies world-wide get too excited about sending a craft to Mars or designing a sojourn with Titan. If one cannot answer the larger questions, it does not matter if the atmosphere of Europa could be finely measured. Answering, larger questions, however is more difficult.

Details, often the noise that destroys elegant solutions, have been dominant in every field. One could argue that an elegant, simple solution to the larger question, even if it is incorrect, is much more valuable than adding yet another particle to the zoo to explain phenomenon that will remain inexplicable with existing theories. Humans seem to be evolving downward, adding skills that aid detailed analyses – but losing the ability to see the bigger picture. Part of the blame has to go to educational systems worldwide – masters of creating cogs in the wheel, adept at taking standardized tests and soaking up text-books from the past, most of which have become irrelevant. Further, hiring managers in the dying behemoths, trained at conventional techniques prefer those who can deliver next quarter’s earnings at the expense of a valuable enterprise. 

We could be tending toward a world of engineers, doctors and scientists – who have no interest in answering why we are really here.

Light chip

Recent research from the University of Utah seems to get closer to silicon photonics and faster light based processors, many orders better than conventional products. Splitting light has always been easy but Utah engineers have accomplished it with beam splitters of a mere 2.4 microns of size. This may propel us out of the ongoing rat race of packing silicon ever closer on conventional chips for less interesting performance improvements.

Moore’s law, held sacred by technologists and used by exponential curve plotting, singularity seeking intellectuals, for stupid predictions, may have done significant damage to the psyche of innovation in electronics. Humans, grand optimizers of their limited life horizons, always fall into the trap of incrementally improving what is available. They appear to be satisfied with metrics that double over long horizons – such as years and this is in stark contrast to their keen awareness of limited time. With less than a thousand months of life span, a metric that doubles every 18 months appears so much less interesting than one that explodes by a few orders of magnitude in the same horizon. More importantly, doubling computing power in 18 months with no perceptible impact on existing applications is a waste of time.

It is time to throw out processes that grow within the same orders of magnitude every year – they will certainly employ people, but they will not make any difference to humanity.
