This spoke to me for two reasons.
1) Plenty of professions are like this. Lawyers, consultants, doctors, bankers, stock brokers etc. Everyone thinks that their profession is the 'best' one.
2) As someone in tech, but not a Software Developer, the number of times I've gone into technical conferences (yes, even the 'inclusive' ones) and got the feeling of being lesser just because I don't write code for a living bothers me. In particular, the stigma associated with being in customer facing roles (particularly sales) is strong.
That said though, the developer-oriented tech conferences definitely skew towards "rockstar" in terms of who is popular and I mean that word in the most negative sense possible. I have found this especially true of the "inclusive" ones. I feel sick around personality cults and avoid more and more of these.
As someone who develops for a non-technical industry, I've gotten a lot of sneers from other developers when I explain my company and role. At the end of the day though, I have 10x as much responsibility and appreciation at my job than they do in theirs. I'm leaving my job in ~2 weeks and I've had half a dozen exit interviews with people in different roles here and even a C-level (a real C-level, not a startup C-level) from another office across the country flying in just to have a meeting and say goodbye to me. How many "average developers" (because that's all I am) get to have that level of impact?
