What the difference? Do you think people pretend to be interested in a product when marketing is good? I think they become genuinely interested. People pretend when there are some benefits from pretending, social or monetary or whatever. I can say for myself that my excitement about space is genuine, but I cannot say is it a result of the marketing. When two Falcon 9 boosters land side by side with a sub-second interval is it marketing or engineering excellence? I do not care, I like that moment, it seemed unreal at the time, it changed my perception of what is real and what is not. In other words it changed my perception of reality. It is a big deal, and I cannot care less if it is a marketing.
