Competitors are also multi-billion corporations. I do work for one of those big multi-billion corporations, it's my second, and I've also worked for others not so big. Only newbie engineers fresh out of college believe the myth of the genius engineer who gets grossly overcompensated because they're so smart. You can find 10s of thousands of brilliant engineers in any of these companies, that's the bottom line. Not a single one of them is, on their own, irreplaceable. Specially valuable individuals get awarded distinctions like "fellow" or "distinguished". They're valuable, more than anything else, because of their contacts and rapport within the industry. It's never technical competency; not that they're technically incompetent, but most of their underlings will likely be more technically competent than them (if they're smart, after all, they will do the technical work). If you haven't figure this out yet, don't worry, you'll get there.
