There are chips in everything nowadays. You don't need to be on the leading edge to be profitable. The 12/14nm and 28/32 whatever they want to call it, will be in production for another 20+ years with more and more demand as products on bigger nodes transition and newer products and newer gadgets come to market. In fact the not bleeding edge products make up the bulk of the market and have expanded many times faster than the bleeding edge. You just don't hear about 1,000+ chips in each modern car or multiple chips in remote controls, smoke detectors, batteries, surge protectors, fly swatters, etc.. whatever you can think of. Everything has chips nowadays and the majority are not leading edge.
