I wouldn't underestimate the need to associate positive emotion with AR in the early stages. Technophobia is a natural reaction when technology can alter our relationship with our environment. The opposite of silly can be unsettling. The Facebook social network is primarily a consumer product. Focusing first on applications with more societal value but narrower appeal (therapy for example) would be a business mistake. The stakes are also lower. No one gets hurt if a hat is misplaced on your shoulder. It is a misallocation of effort if maximizing social value is the goal. But it's not. Profit is an imperfect proxy.
