However, in my personal experience, it is not an accurate summary of the Bay Area. The startup scene may be truly this toxic, but I think such toxicity plagues any small, homogeneous group of people. It is hardly a tech problem. Indeed, mom-and-pop shop in small towns can be very abusive too.
To offer a counter anecdote, my experience with FAANG has been very positive. My workplace is the most meritocratic, efficient, and transparent organization that I've been in. (And I did spend 6 years on the East coast doing things unrelated to tech.)
I'm certain that the author's experience is true. I also want to caution against generalizing these issues to all of tech in the Bay.
