There are severe misconceptions in this hypothesis, or at least in the examples that are being presented. When you are introducing yourself, you have to refer to yourself explicitly. You are trying to convey information about who you are and what your background is. That's not a sign of low status, it's a necessity to transport essential context. If you try to leave that information out, or if you just omit the pronoun, your introduction will inevitably sound broken or unfriendly. I'm guessing the reason why this is being conflated with low status by the professor is simple: if you're high-status, other people initiate contact a lot more often than you do. And when they initiate contact, they need an introduction, whereas you are already known to them. At a fundamental level, this hypothesis as it's being described muddles correlations and causes. Secondly, I'd like to point out that clearly marking certain points as opinion does not come from a perspective of inferiority or uncertainty. Especially in a setting where discussion is warranted, such as here on HN, it's an appropriate signal. When I refer to myself and my perspective, I'm not asking you to disregard my point of view, I'm inviting you to see things from where I'm standing, and I'm also inviting you to present other perspectives without either of us being pressured to lead with assertions like "WRONG! Here's how it really is: [text]". Instead, you are afforded the option to respond with "My experience has been different. Here's why: [text]".
