There's no "just" about being a technologist. There isn't a pecking order of this stuff. But yes, most invention and applied science and making lives better and people live longer and in greater comfort is done by engineers or inventors. Not scientists. Engineers and inventors apply the theories that scientists have discovered (or sometimes just use their gut knowledge in clever and unexpected ways). Sometimes scientific theories turn out to be wrong in subtle ways, and the scientists refine them, which can lead to new applications from the technologists and engineers. Me, I'm an engineer, which is of course a much higher calling than being a scientist.
What Thatcherite said. Except I'm a mere scientist. Of my 3 sons, there's an engineer, a doctor, a scientist, a lawyer, 2 software designers, and a CEO (yes I can count). No hierarchy, they're all the greatest thing since sliced bread.
Thanks, Thatcherite. I definitely couldn't have said it better.
