Mr. Tom Packalén:

I thank the witnesses for their excellent presentations. It is interesting to be here and to listen to all of them. I thank Ms Cadwalladr and Mr. McNamee for their great job of work in regard to Facebook and the Cambridge Analytica issue in particular, which was very bad for artificial intelligence, AI. It showed both sides of what AI can do. We had thought AI could be used only for good but it can be used as a weapon to do bad things.

There are many problems that need to be addressed by way of regulation, including hate speech, fake news, identity bubbles, election influence and interference. There are also many algorithmic problems. What is the biggest problem? Where should we start to solve this problem?
