In most cases, I think they are a solution waiting for a problem. Let the code grow organically at first and see later if a design pattern helps make it simpler, because we humans are terrible at predicting things, moreso the abstract ones.

But getting lost in a sea of abstraction is easy, it makes you a better architecture astronaut than the one that's sitting on a Tesla now on the orbit listening Bowie's music. Looks good, makes you feel an expert, but really it's almost as bad as selling snake oil.

We programmers, as a whole, should have a code of ethic conduct and a better moral ethos.
