Funny to read this after reading the Claude Shannon profile posted a few hours ago [1]. An actual giant of 20th century mathematics, and so humble.

Moreover, it should be obvious to Wolfram that his incessant self-promotion greatly reduces the probability that a reader will recommend his writing to their friends -- if Wolfram's goal is to promote his software, research, or even just himself, then he's clearly going about it in a ham-fisted way.
and then there are true extroverts, who just need the feeling of being hot topic, controversial, whatever. to be polite i don't like these so much.
of course i don't know him personally, could be different reason but probably somewhere along those lines.
However, there is a surprisingly high amount of high school and science bachelors, including math, that actually does not know about it (or other cas for what matter). Each time I am quite stunned by it, and it does not seem to improve with time.
I should start making a proper survey if next year I teach a first year course.
