Design is not a thing that can die. It will exist for as long as the human race does. And so will shallowness, tastelessness, ignorance, self importance, agendas and marketing turkey cocks. Don't mix them together my friend, cheer up.
Your design structure will be affected by dark patterns soon or a later. I think that you don't have enough experience to comment on the situation at all. Marketing will have access to your design process eventually. Then we will speak again.
