Who I am to judge what innovations are useful or useless to society? In a sense, one could very well argue that the market cap or valuation of a company is at least a decent proxy for "usefulness".
With that said, however, my personal opinion is different. Although I think innovation of any kind is great for society, what I'm frustrated by is the relative mindshare of where we focus our attention on.
I like to use the term "farsighted" - many people in SV are able to see very far distances into the future, but ignore some of the immediate problems that are right under our noses. That's what I'm frustrated by.
