Very true, and it's not just creepy elites either. Before I got into tech I worked a blue collar job that involved zero emailing. When I first started office work I was so incredibly nervous about how to write emails and would agonize over trivial details. Turns out just being clear and concise is all most people care about.

There might be other professions where people get more hung up on formalities but my partner works in a non-tech field and it's the same way there. She's far more likely to get an email dashed off with a sentence fragment or two than a long formal message. She has learned that short emails are more likely to be read and acted on as well.
