We Have Reached the Limits of Computing Power, Says Supercomputer Expert

Some of the world's leading engineers and physicists believe we are about to reach the limits of computing power, requiring a fundamental technological shift which we have yet to imagine. 

What's the Latest Development?

Due to some rather strict physical constraints, the kind that come when working with atoms, we have nearly reached the limits of computing power, says High Performance Computing expert Thomas Sterling. The last major computing milestone was achieved in 2008 when the Los Alamos' Roadrunner supercomputer reached petascale computing, or a quadrillion (10^15) floating point operations per second. But Sterling says we are unlikely to achieve Exascale computing (10^18 FLOPS) "without ripping  apart our existing ways of building supercomputers, root and branch."

What's the Big Idea?

Since the dawn of the supercomputer, the world's best engineers have been able to create a next-generation machine with 1,000 times the power of its predecessor in cycles lasting about eleven years. The trend follows Moore's Law, which states that computer power doubles roughly every 18 months. Like Sterling, physicist Michio Kaku also predicts that we will reach the end of Moore's law within ten years. After that, we will transition to 3-dimensional chips, and eventually to quantum computers by the end the of the 21 century.

This 5-minute neck scan can spot dementia 10 years before it emerges

The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.

Mind & Brain
  • The study measured the stiffness of blood vessels in middle-aged patients over time.
  • Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
  • The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.

How 'dark horses' flip the script of success and happiness

What defines a dark horse? The all-important decision to pursue fulfillment and excellence.

Big Think Books

When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
