This is a pretty dumb response, not only because the idea that knowledgeable people matter ≠ knowledgeable people are the "only people that matter," but also because the alternative that you're crowing about is that nobody matters (other than you, the person selling the thing.) You're accusing people of being narcissistic for wanting any information, and bragging about only being guided by your own desires. It's really a moral toilet.

The "tech nerds" is a bullshit term for "people with the background to understand the explanation." If you're not explaining it to them, you're not explaining it to anyone. You're just subjecting everyone to your whims, and really should be regulated into the unemployment line.
