May I add something about GDPR?
I worry about the next step. You have to expand what it covers. You have to address not just the data that people put into these systems but the data that is systematically gathered about them through acquisition from third parties, through surveillance tools like Alexa and through web tracking. The fact that none of that is covered is a huge issue.
Then obviously you have to have a regulatory enforcement policy that puts teeth into it, because the fines are trivial and the processes take way too long and none of that's having any impact. You can see that fines of billions of euros have no impact on these companies. It needs to be tens of billions of euros and it needs to be every month. You have to get their attention. Right now, Facebook wants to move everything to the current version of GDPR because it prevents their competitors.... The cost is so much higher on their competitors, it's an enormous advantage to them and it doesn't touch any of the surveillance capital concepts that they're excited about.
The stupidity of Facebook and Google was that they didn't embrace it right off the shoot and actually implement it.
