Another supporting argument for this is from The Innovator's Dilemma: disruptive technology (startups tend to leverage this) tends to be constructed from pre-existing and commercially available components. Think Snapchat, Instagram, tablets, digital pianos, and all-in-one PCs. All the major building blocks had already existed at the time of invention. This is in stark contrast to sustaining technology, which tends to require expensive teams of scientists and engineers to make incremental improvements to an existing business line, making it palatable only to large organizations with deep pockets. Samsung can afford to have its physicists to find tighter SSD data packing. Google can afford statisticians to tune their search algorithm with complex models. Startups simply can't, nor should they!
