That was one of the things that destroyed NCR after AT&T bought it. AT&T had no technical career path, and effectively cut its own head off.

As a result, AT&T bought NCR for something like $9 billion, and ended up spinning it off for something close to $3 million. My mother was at the time an IBM exec (since retired), and she was ecstatic -- IBM was much bigger in the US, but until AT&T bought it, NCR dominated the international big iron market. AT&T effectively killed off IBM's biggest competitor, and a major part of that was the fact that the entire company culture was optimized around funneling talent into management or out the door.
