IBM felt to me like the last holdout of the shiny shoed salesmen when I briefly worked for them. Before the internet and big tech companies with leaders who were theoretically technical there were the companies dominated by salesmen because selling was the critical part. I imagine that getting a board to spend a lot of money on some project is hard and you need the support of the kind of people that can influence boa…
Agree with you that many of the salesman are typically technology-agnostic [I use the term "agnostic" in the sense it is used to define religious belief :) ]. They have capable technical guys supporting the salesmen, though.
