I 100% disagree. Have had extremely interesting conversations out of essentially this question regardless of my status relative to the person I'm asking (plus or minus 3 levels in the management chain), except in the rare case that the person is so super shy that they can't come up with anything to say even with coaxing. People that don't give a shit about me are even more interesting when they answer.

With a person who is higher status than you, they invariably have a life story that they are practiced at and enjoy telling, and know how to answer this question in a really satisfying and engaging manner because it's been asked so many times. That's the easy one, and pretty much no high level person will be upset if you ask.

It's toughest with someone not used to answering this question, or someone who thinks of you as higher status - in those cases, you can't just say "tell me about you", you have to make them comfortable and coax them into getting excited to tell you about things they care about. That requires active attention and listening, and is not necessarily easy.

Asking people to tell you about themselves is never rude, in any case. If your conception of "rude" includes that, then you're gonna have a rough time in all but the most wonky parts of business.
