I don't see why this has to be considered a problem. Of course there should not be any forced barriers to women in engineering - or men in nursing for that matter.
However we should not be modifying engineering to make it more appealing to women. Is it possible to do so without changing what engineering is?
Statistics only give you a generalization and women tend to be more interested in nurturing than engineering. Of course there are individuals who don't follow those generalizations and they should be encouraged to follow their choices.
Removing gender barriers does not mean the same thing as achieving a 50:50 ratio in all professions. Here in New Zealand we have been very active at balancing the field. We have had two female Prime Ministers in the last 4. We have openly gay and trans-gender politicians. We have more females graduating as doctors than males. We have more females graduating than males. Yet engineering is still skewed towards males.
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.
