Also, your accusations against growth hackers are titled based rather than what they do or learning about what growth hackers do. If growth hackers choose to identify themselves with each other in a new way, I don't think there is an issue. Let them be. Remember, front-end engineering wasn't considered much of a position 5 years ago. Same with UX, UI, data scientist, etc. How about SEO specialist or direct-marketers.... Can they self-idenitfy a new sub-division of marketing?
Adam Smith was right, people specialize as an industry expands to offer greater value in a niche. Growth has become essential to startups. Growth teams are becoming standard at scaling startups. Thus, growth hackers appeared.
It is fine to express a distaste for a growth hacker by what he or she does, seems silly to dislike them for their title. That is like saying "I hate chocolate because of they call it "chocolate""
I must say degrading the work Sean Ellis and Andrew Chen have done by comparing them to meaningless consultants from the dot-com era is disgusting. Andrew Chen is one of the most brilliant viral engineers on this planet. Sean Ellis has rocketed several companies to success and just acquired a KISS company. I don't respect ad hominem attacks, neither should you.
