I think people use "laws" out of optimism--they really want to improve our predictive powers and "wish" that they could come up with a black-or-white "law" to help out. Of course, as you say, the world is shades of grey :)
The Higgs Boson was confirmed based upon a statistical observation and now most particle physicists believe the standard model to be accurate. I don't see a problem with claiming something is a law if the statistical analysis supports the claim. Even our own existence is based upon statistical interactions with photons. If you don't believe that, turn off all the light in your bedroom tonight and tell us tomorrow if you could still see yourself in the mirror.
Moore's law is not a law,people don't give a shit about it! it is a trend for the company to follow to make money which in this case flawed due to major miscalculation of not taking into account of the whole semiconductor eco-system.
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.
