I'm not going to say antitrust is.... I'm from antitrust. I worked at the Department of Justice for many years before teaching. I could see the power antitrust can have. It's not the silver bullet. It's necessary, but it's not sufficient.
You do need to re-amp the tools, the way you point out. We talk about this in our book, Big Data and Competition Policy, and there was a report that came out by the Canadian Competition Bureau recently on big data.
I've seen the work the European Commission is doing, and what the French and German competition authorities, the CMA from the U.K. and Australia are doing. Now the United States is starting to have hearings on this as well. This is a key component that any competition authority needs to ramp up to better understand the risks in this economy. There are multiple risks that we didn't even talk about today.
