moments of stress where it matters most is where human judgment is most valuable. the traders on the floor aren't going to stop major market movements, but they're going to make that micro volatility, the small round about the edges which saves investors money. we have seen a degradation since we closed the trading floor. >> reporter: is there a symbolism to having the new york stock exchange trading floor open? >> without a doubt. the facade is the face of globalism and our economy more broadly. so recognizing the fact that we can set an example for how america should reopen, slowly, cautiously, flexibly, ready to move as needed is an important thing for our economy more broadly as we look to get it st >>eporter: but the tray. p.p.e. like face masks will be required along with social distancing, and there will only be about 25% of the normal trader work force on the floor. around 100 people.

make sure t'm stopped.orte fish call for extreme measures. but big brother really is pretty much keeping tabs on you. why did russia go that route? >> because russia is a totalitarian political regime. what we actually see is lack of trust between the government and the citizens. so it's very hard for the government to simply ask to do something from the people because the people would not obey because they do not trust their government. >> reporter: once life returns to moscow, the government says it's going to delete all the data it's collected. but it is not goingowhat lrned technology and social control. i'm elizabeth palmer in london. >> china is using the coronavirus lockdown in hong kong to tighten its grip on the
