I've been drinking tonight, and when I'm drinking, I start thinking about off the wall topics. I'm a computer scientist, and there are several abstractions between my area and the physical world. Before one ever gets to my world, he or she must go past the layers of nature, physics, basic electronics, digital circuit design, logic gates, some architecture like Von Neumann or Harvard, assembly language, programming language, oceans of math, and finally into my area of machine learning. The problem of having a field like mine is that a Neil Degrasse Tyson lifestyle is simply off the table. When one is in a highly discretized field, he or she can't point to some physical object to explain to grandmother what exactly he or she does. And there is a deal of loneliness in such a thing. Can you explain what you do to your grandmother? Why or why not?
