David, this is a very interesting topic. AFAIK, stripping PCBs goes beyond the hobbyist level and sometimes enters the real market.
I know a real case in which a Chinese company sold a lot of low-cost LCD displays that were stripped from the PCB included in obsolete Japanese toys to a company developing products for the domotics market. Of course, I won't tell you the name of the company which bought the displays, but I can assure you that they gave me this information only some months ago -- and they were soooo proud of doing this ;-)
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.
