Almost every human being reaps the benefits of our technological and scientific progress in some way, but only a small portion of us contribute to it.
Of course, there are plenty of other important areas of work, but it certainly wouldn't hurt to have a higher percentage of people be interested in this stuff.
It's just so crazy, that using "cutting edge integrated circuit R&D" as an example, there are maybe what, a dozen people in the world who are intensely familiar with that ecosystem? And yet it forms one of the pillars of our entire modern world.
I think people in the medical field are probably the most important, though. Can't do science or write code if you're sick, so I have an intense appreciation for them; they help all of us.
