If we are, in fact, alone in this universe, there are two ways to look at it. First, the way you concluded: "it would behoove us to take good care of each other and of the planet we call home"
From another perspective, in all of those trillions of stars out there, if we are alone, then we are such a small component of the whole as to be completely insignificant. We are a tiny spec of dust to brushed off and never thought of again.
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.
