OK, there is a serious disconnect between true programmers and sales people.  It is a gulf most programmers can't span.

Code is truth.  Code is beautiful.  There are no lies in code.  There can be no lies in code.  Every instruction is executed exactly as written.  There is no fudging.

In sales, it is telling a story.  It is getting other people to believe that story.  And so many of the people that are good at sales are really good at story telling and often very poor about things like truth.

To a coder, the code itself is what sells it to them.
That is all there is.  There is no need for anything more.

To a normal person, the code is a black box that even on their best days, they cannot see what makes it work.  At best, they see the paint job on the box.  And make their purchasing decisions based solely on the paint job.

So, a coder cannot talk to, or even trust, a salesman.  There is too much disconnect in their world views.

One of the destroyers of a company, for a coder, is the sales team.
To a coder, the sales team goes out and makes impossible to fulfil promises.  And then moves the dead line creepingly forward.
Its like the sales team doesn't understand at all, even though hours were wasted trying to explain it to them.

The gulf is too wide to ask a coder to get on with marketing.
