Yes - it will be interesting to see which way the industry moves. I think we are facing more physical limitations and challenges than we ever have in the past and it would be amazing if the whole industry always picked the same way.
I know this isn't the theme of the article, Brian, but one can avoid--or at least postpone for a couple generations--many of these challenges by moving to FD-SOI at 28nm or 14nm. FD-SOI is Faster, Cooler, and Simpler than alternate processes and, because it is planar, doesn't require the different design and processing that FinFETs need.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
