Hello, I did not know about these advances, there are so many things, but I think it's great, especially the one that can open the doors to receive someone, it's crazy, it seems unbelievable that this kind of devices can replace human activities, but as I said and thought the technology is excellent and does not help to minimize certain activities, it does not make life easier, but at the same time it displaces human work, which I think is not so good. Many people need to work and it is absurd that a robot can displace you!
