Moore’s Law – Key to Understanding the Techonomy
The fact that technological power comes in smaller, faster and cheaper objects is a very important observation that underlies many of the phenomena around us today.
Since our last post was about education, we decided to talk about Moore's Law today, a trend we all need to be aware of in order to grasp how rapidly the power of technology and thus innovation is increasing.
They say a picture is worth a thousand words, so let's start with the one that photographer Brett Moore recently put up on Flickr, which has been making the rounds on the Internet. The picture shows two familiar Apple products side-by-side: a vintage aqua bubble-shaped desktop iMac circa 2000 and this year's sleek black panther iPhone. Below each product is a list of their capabilities, which on close inspection are incredibly revealing: First, the iPhone is much smaller than the iMac - over 100 times lighter in weight; second, despite the difference in size, the iPhone has double the processing power of the iMac; and third, the iPhone is three times cheaper.
The fact that technological power comes in smaller, faster and cheaper objects is a very important observation. In fact, it underlies many of the phenomena you see around you today such as higher resolution digital cameras in phones and cheaper sequencing and analysis of DNA. It also gives you a glimpse of the future - a world of tiny machinettes that will be your household companions, and a net of sensors that will coat your home making your life simultaneously more convenient and more public.
This trend was first observed by Gordon Moore in 1965 and he later projected that the doubling in processing power occurs every 24 months, i.e. it exponentially increases. Why is this the case? Processing power or the instructions the computer can perform per second has risen because more transistors can be fit per silicon wafer and because the multiple core processor micro-architecture has improved (layman's lingo: more can be done with less - less space and less materials for the same power also means less cost).
There will come a time (some say in 10 years) when we won't be able to fit more transistors onto a single chip. At that point, the only way Moore's law can continue is if we switch from improvements in scale to improvements in structure and materials. Quantum computing holds some initial promise as a model that can not only continue, but increase the rate of Moore's Law. Regardless, at least for the next decade, we can expect technology to pervade our lives in leaps and bounds, becoming ever more powerful even as it becomes ever more invisible. Think about that as you plan your career and your investments.

Can sensitive coral reefs survive another human generation?
- Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
- The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
- If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.
They didn't know it, but the rituals of Iron Age Scandinavians turned their iron into steel.
- Iron Age Scandinavians only had access to poor quality iron, which put them at a tactical disadvantage against their neighbors.
- To strengthen their swords, smiths used the bones of their dead ancestors and animals, hoping to transfer the spirit into their blades.
- They couldn't have known that in so doing, they actually were forging a rudimentary form of steel.
Michael Dowling, Northwell Health's CEO, believes we're entering the age of smart medicine.
- The United States health care system has much room for improvement, and big tech may be laying the foundation for those improvements.
- Technological progress in medicine is coming from two fronts: medical technology and information technology.
- As information technology develops, patients will become active participants in their health care, and value-based care may become a reality.
