Not in reference specifically to product roles, I think one of the problems right now in SV and probably in other tech hubs is the migration of finance, law, "other fancy profession" people to the tech industry as the bubble has inflated. You have lots of people who genuinely have no qualifications specific to the tech business and there only drive is to just follow the path to whatever is shiny and looks like the most possible path to extravagant wealth according to Forbes. Usually they are easy to identify because they transform themselves to fit the mold of whatever is hot.. ex. in 2004 they were real estate agents / brokers, in 2008 they were social media consultants, and now they want to be SV product / tech entrepreneurs because it the latest things in the paper. The problem with these folks is they unfortunately add little to no value because they spend all their time running around trying to figure out what is the cool thing rather than trying to understand how they can use their own skills to best help others.

Honestly Im not too big of a fan of the bubble times. I'll be glad when things calm down and the finance, law etc types move onto the next shiny thing and were left with the people who truly enjoy the industry.
