During the industrial revolution, humans were also afraid that machines will take over the world. It turned out that not only they didn't, they actually helped humans become more efficient and we can focused on more intellectual work due to machinery.
Forwarding time by 250 years, we are once again witnessing a revolutionary technology being born. Will robots and AI replace humans? My short answer is no. I think that robots and AI will replace some jobs that humans are currently still doing. Especially those that require repetitive manual effort. I am not just referring to menial work at shipyards or factories, I am also talking about jobs like legal proofreading, financial auditing and security events correlation. The list is endless but the sky is not going to collapse overnight. So if you are working in those areas, do not panic... yet.
With humans freed up from manual repetitive work, we won't lose productivity as a whole. Instead, I think we will be even more productive, creative and inventive. The key difference between an AI/Robot and human is that human can create something from nothing, while AI/Robot cannot. That is because AI/Robots cannot recognize problems and opportunities when there are.
AI can learn based on what they are programmed to learn. You can program an AI to identify faces better and faster with each iteration. But in the first place, they would never have the idea that facial identity is important. You can get them to learn what are fake news and what are not. But they will not know that fake news is a problem in the first place.
You see, the value of humans is that we are able to keep thinking out of the box and improve our productivity along the way. We are also creative in the field of arts and music. These are things that I think AI are not capable of. I view AI/Robots as useful tools. Imagine if AI/Robots are able to help us with very rapid prototyping. Our jobs will literally be just dreaming. As we think of an idea, a prototype is already being built and we can immediately see if it works or not. So much time and effort would have been saved!
Personally, I am looking forward to the day which I can just lounge around and dream of ideas while I let AI take care of the menial task of prototyping/testing them. :)
