The salesmen have adapted to a new style with smart casual clothes. They have a new vocabulary and perhaps ride mountain bikes instead of playing golf.
They still mock technical knowledge by wading around in a new sea of acronyms which they don't truly understand or care about. Think of the CEO of a company that makes a build system - every 10th word at one point in time might have been "CD" which means Continuous Delivery which is something his own company never did. But it's the most important thing in the world for that year or two and lots of sententious things are said about it without any connection to the possibility of "walking the walk" to use one of their favorite and least honest terms.
As a technical person one listens to them and wonders what planet they came from and how they could possibly have any connection with the reality of the business they're supposed to be running. But... they're salesmen and have sold themselves as the first product. They know what impresses non-technical people and it isn't the plain honest truth.
I think it boils down to some facts: we have it better than it has been for a long time but there are real situations where one must be a master of bullshit and have the ability to appear supremely confident and all-knowing whilst actually knowing very little. This confidence founded on nothing transmits itself to other people. If you are lucky and appear to be a winner or if you can hide your mistakes and advertise your success then people will take your lead or offer you opportunities.
