This was a totally misguided re-branding of the field. It attracted bureaucratic personalities and classist managerial types, and utterly destroyed the field.
Like you, I couch my job description: I'm a "Systems Software Developer, I develop software systems" .. because its true, thats what I do, even if its a majority of the time working on embedded projects.
And if someone then responds with "ooh, so you're in IT", I immediately go to another corner of the party and avoid them like the intolerable bores they are ..
