A related concept is the "Pentium mentality", the notion that any technology will drop in price next year. You don't need to explain why the price will come down; it just happens.
Many people use that rule to explain why electric cars and solar cells will be commonplace soon, when it is obvious that they are way too expensive to be practical.
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.
