Just because the label on the chip is housed in a particular country doesn't mean the manufacturing is done there... doesn't mean the design work is done there... doesn't mean taxes are paid on the profits there... doesn't say anything about who owns the shares of the company.
I'm not knocking the accomplishment of U.S. companies, but especially for one with an engineering mindset it's worth noting that these numbers capture only a small bit of the economics behind our industry.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
