I was going to make a broader point about data, which has come up as well. It's important to consider that for Amazon, Google, Facebook and many of the technology platforms, the reason this business model of hoovering up as much data as possible is the basis of what's been called “surveillance capitalism” in how they make their money. More so, too, there is now this vertical integration between the data and the compute power that they are amassing with the hardware.
Facebook has built one of the largest supercomputers in the world, so the scale of the data that these companies have is something that will have many ramifications on the shape of markets in the future. That is a really important question for regulators to be actively thinking about and considering.
