Frequent security expos feature companies like Megvii and its facial- recognition technology. They show off cameras with A.I. that can track cars, and identify individuals by face, or just by the way they walk. In China it's been projected that over 600 million cameras will be deployed by 2020. Here, they may be used to discourage jaywalking, but they also serve to remind people that the state is watching. Matching with the most advanced artificial intelligence algorithm, they can actually use this data, real-time data, to pick up a face or pick up a action.
A.I. is a technology that can be used for good and for evil. So, how do governments limit themselves in, on the one hand, using this A.I. technology and the database to maintain a safe environment for its citizens, but not to encroach on a individual's rights and privacies?

One of the Universe's most enduring mysteries is Time Travel. In this episode, we explore the possibilities. Discover why Time Travel into the future is unavoidable in the Einsteinian world of Relativity. As for the past... the laws of physics do not tell us it's impossible, but the bizarre consequences of going into the past and altering the future make for mind-bending science. Finally, we go for the future by traveling to the nearest star, 4.3 light years away... in only 45 days. Our destination may be an Earth-like planet; a planet scientists are now hunting for, and may find in the next 3 to 4 years.

When it comes to illusions, optical illusions get all the attention. But the whole body you have can be fooled and can fool the brain. What is touch? Is it real, or is it just in our heads? Michael Stevens decides to find out.

This is the story of Gerald Cotten and the many people who ended up with empty bank accounts after investing in his Bitcoin cryptocurrency exchange, QuadrigaCX. What does a crypto exchange do? The movie explains it concisely and it almost makes sense: A guy like Cotten takes an investment, converts it to Bitcoin and trades it in hopes of turning a profit, kind of like a stock day trader does. Cotten ’s described as a nerdy guy who felt like an outcast, but found a community of like-minded types in the cryptocurrency world.
Cotten was in India when he got sick and unexpectedly died; he was 30. At the time, QuadrigaCX was Canada’s biggest crypto exchange, holding north of $200 million. But nobody could access the keys and passwords to the company’s accounts and, against conventional wisdom, the company had no safeguards to stop such a thing from happening. Everyone who invested their money was left grasping at empty air. Internet forums foster ideas such as Cotten faked his death and took the money. The journalists and forensic accountants who lend the voice of reason, explores the oddities in the Cotten narrative, ruling out some of the crazier stuff in a quest for the truth.
