Steve makes a good point that the largest technology companies have stopped (boldly) innovating. Obviously, all the engineers at the companies still go to work and write code. But with 10x the resources they seem to be outputting 1/10th the innovation. What are the bold innovations to come out of Facebook, Google, Microsoft over the past decade or so that haven't been acquisitions? With Facebook, you have a bunch of work on better targeting ads. Oculus and Instagram are both acquisitions. Amazon is the exception. With Amazon, you have AWS, Alexa, Fresh/Prime Now, while also breaking into new geographies and verticals etc.
