I'm not familiar but I watched the video and its so funny and entertaining. The way the AI speaks.
It's fictional but it can really happen. There are people who can use AI robots at their own benefit. This may sound ridiculous but, we can't really tell what technology we can discover after a century.
Again it depends on the maker of the Robot. If the robot is programmed to do certain tasks and even do destruction it's really possible. There are advantages and disadvantages to technologies that we are facing, just like the anonymity of cryptocurrency that is being used in illegal transactions before regulations took place.
Several things that started in movies have become a reality today but not everything that we have seen is also in existence as at today example is the time travel machines, cloning of people, existence of super heros etc. AI existence continues to grow and they continue to make life easier but one weakness that they have is that contrary to what we see in movies, they are existence is still very dependent on human intervention. There is a Google AI system that if I choose to turn of remains off. Robots needs to be charged, they needed to be fed information for them to function, they can be corrupted and the shut off. So, there is no need to fear as to whether they would take over the world.
In technology, everything is possible in time and thorough research. There's no definite time but it's really possible. When we talk about time travel tell me your thoughts about this video. Is it really true or just a made up story by the speaker.

Another video about cryogenics. This is somewhat fictional and impossible but we really don't know few centuries from now everything will be realized.
