I see in a lot of communities without mention anyone that there is a lot of people that actually rude with newbies and they link the lack of knowledge with the lack of intelligence, and I don't know what the relation between them, maybe this person has a knowledge in something else you don't actually have!
I am really amazed at how people, often without any awareness, are persuaded by banks and companies to buy more and more even when they don't actually want the product. I am also amazed by how our minds allow us to feel a sense of satisfaction after buying something we don't even need.
I agree with that as well, the "why" explains the business logic and that makes much more sense to me. Otherwise, I might end up explaining the algorithm (the "what") instead of the business behind it.
I really liked the story; the technology can indeed change our mind gradually and make us accept things we once refused. This actually made me ask: how do we rearrange our ideas based on that?
