The perils of incessant experimentation. The "throw it up against a wall and see what sticks" method. Good for testing spaghetti, sending out college applications, and ... for technological innovation? Google seems to think so. The company has famously introduced a myriad of now-defunct services — ones that didn't pan out as expected such as Google Wave and, more recently, Google Helpouts. This kind of innovation is bold, and not a bad strategy so long as something does, eventually, stick. Specifically, something profitable. But there are no guarantees, and some draw parallels between Google X, the research lab responsible for Google Glass, driverless cars, etc., and Microsoft Research. In both cases resources have been directed toward lots of flashy ideas that, in many cases, ultimately lack in financial follow-through. Of course, Google CEO Larry Page has famously prescribed that the company will now put "more wood behind fewer arrows," meaning that Google will place more focus on its key projects. Still, those arrows need to be chosen carefully, and investors are worried that an excess of Google's attentions are directed toward ancillary aspects of the company.
