Oh my god it isn’t ironic. These people read it and thought it was just tech and bro in the cool sense.

Gather round children and let me tell you a tale about a time before it was broadly trendy and profitable to do technical work, when bros sold mortgages and stayed in sales, and we were all geeks and nerds (whether we identified as that or not).

"Bro" is a strange word, because it has gone through quite a bit of semantic shift. It used to refer to a certain type of entitled, right-wing young male associated with some college fraternities (not all frats are like that, but a lot of them are) and tech-company management. Now, "bro" has just become a synonym for "man" and doesn't really have the sting it used to have.
