No it is not ignorant. You are ignorant, LOL!
So many people get a bunch of artsy crap ideas and then implement them breaking simple easy to use workflows. You cannot convince me other wise.
On the other hand, I did mention that to keep their jobs there is churn, and you just mentioned one of the reasons for it, execs are a problem. Buzzwords are a problem. Trends are a problem.
But I can point to lots of projects that were given a team and time. Particularly worse if they asked users what they wanted because they are some of the biggest morons to ask in the first place.
