Publisher's | LETTER I ’ve been thinking a lot lately about technolog y. More specifi cally, about the ways that major technological advances are going to change the way engineering is practiced. How do engineering fi rms need to react to these changes and what does the engineering fi rm of the not-too-distant future look like? How does a structural or MEP practice change when photo-realistic and super accurate 3D BIM models become the rule rather than the exception? What does your survey practice look like in a world of drones, LiDAR, GPS and GIS? What does your traffi c department look like in a world of autonomous vehicles and how does your transportation department design roads made for cars without drivers? What is scary is how fast change is going to occur. For most of human history to this point, change has been linear and incremental, and humans are well equipped to adapt to linear change. But according to Ray Kurzweil’s “Law of Accelerating Returns,” technological change is exponential, rather than linear. "The reality of information technolog y is it progresses exponentially," Kurzweil says. "30 steps linearly gets you to 30. One, two, three, four, step 30 you're at 30. With exponential growth, it's one, two, four, eight. Step 30, you're at a billion.” The most famous example is "Moore's Law," named for Gordon Moore, the co-founder of Intel. Moore’s Law predicted that the computer chip performance will approximately double every 18 months. It is the reason why the same computing power that once fi lled a room now barely fi lls your pocket. Those advances in processing power, combined with “Big Data” and machine learning, will make possible artifi cial intelligence software capable of performing ever more sophisticated cognitive and problem solving functions… functions that may soon become required tools in the practice of engineering. Trying to determine how these technological disruptions may impact the practice of engineering will be a major focus of ACEC Georgia in the coming year, so I’ve been doing a little light reading on the subject. My “Sully’s Selections” for this issue are three books (all New York Times bestsellers) I would recommend to those interested in thinking about what may be coming sooner than we think. SULLY'S SELECTIONS RISE OF THE ROBOTS: TECHNOLOGY AND THE THREAT OF A JOBLESS FUTURE By Martin Ford Ford deals primarily with the macroeconomic consequences of technological acceleration. What are the jobs that will be replaced by technology and what public policies need to be considered for the day when there are far fewer jobs than people? THE SECOND MACHINE AGE: WORK, PROGRESS AND PROSPERITY IN A TIME OF BRILLIANT TECHNOLOGIES By Erik Brynjolfsson & Andrew McAfee A fascinating, and quite readable, book that ﬁ rst explains the factors that will enable the artiﬁ cial intelligence breakthroughs that are in our near future, and then offers predictions on how this will revolutionize the world of “work.” Michael L. “Sully” Sullivan President and CEO, ACEC Georgia Publisher, Engineering Georgia THE INDUSTRIES OF THE FUTURE By Alec Ross A good overview of how technology is going to change many different aspects of our world.
