 Dear students, now let me take you towards the current era. It is a matter of past that human beings made a tremendous progress and that left the great impact on the population, especially the increase in the population. As I've already mentioned in the past 100 centuries, we have seen the increase billions of people have been added in this global earth and before this, it was not possible for centuries thanks to the development of the agriculture and the industries, thanks to the development of the scientific society. Now let's talk about the era in which we are living today and that is the now post-industrial society. Human beings now are at the peak of their advancement and we are expecting more and more advancement in the near future whether it is in terms of the artificial intelligence, whether it is in terms of the robots are going to take your place and they are going to probably work in our homes as the house help and that will still and that will also leave impact on the population dynamics. Many industrial societies have now entered a new phase of technology and we can extend lenses analysis to take account of the recent trend. Now you can see the world population at the start of the post-industrial society, it was estimated to be 4.434 billion which has now increased to 7.8 billion in the year 2020. Now this is what post-industrial societies can look like. As you can see the houses over there and how it leads towards the further development and the huge buildings and number of gadgets and number of other facilities, so there is a great shift in the human being progress and development. A generation ago the sociologist Daniel Bell in 1973, he joined the, he coined the term, he used the term post-industrialism to refer to the production of the information using computer technology. So how interesting is that? Look at your great researchers, your analysts, they are very far away from you. In 1973, a sociologist Daniel Bell introduced us that we will look at a time when computer technology will be available, which we will enter in the post-industrial era from industries and that is the dynamics of our lives, the characteristics of our lives, the components can that everybody was yet to believe you have a leke aika. Production in the industrial societies, it centers on the factories and machinery generating material goods. Now the post-industrial production relies on the computers and other electronic devices that create, process, store and apply information. Now look at the difference. When there was a beginning of the industry, we could see them, we could see machineries are working, we could see the, you know, factories are relying on the new machineries and all that and after that, look at how a quick shift that we have seen in the last 20-30 years. And now we are pretty much relying on the computer knowledge. Dear students, if you talk about the, if you take advantage of the COVID situation that I am talking to you, if from today, 50 years ago or 40 years ago, COVID would have come, such a big pandemic would have come, then the world had to die of poverty, unemployment and hunger before COVID, that was the reason, that time we were 40-50 years ago, if we had to face this sort of pandemic, people were not able, the economic effects of COVID have come, because of that, people's jobs, people's poverty, and we were not like that, that we could be full of people, we could be seen as being at a very big suicide rate and the economic crisis, maybe even before the disease, would have caught people and killed them. Now look at our industrial development, our post-industrial development. Our computer has saved a lot of mouse shows, despite of that, that this pandemic has come to the world very quickly and it has disturbed us, there is work from home, with the help of the computer, a lot of people have been able to keep up with the work of the world, people are getting their pay, education system is going on through the computer, so these are the changes, these are the dynamics which science has given us. So just as people in the industrial society, they learn mechanical skills, people in the post-industrial society, they are very much into learning into the information-based skill and carry out their work using computers, just like I was talking to you. Nowadays, there is a lot of talk, IQ, artificial intelligence is your talk, reports are being mentioned, how different inventions and discoveries are being seen every second day. So these are the changes and we have connected more with each other. And along with that, of course, when our analysts, our sociologists, probably on the negative side, if we talk about it, we will also see the impact of it on our society. In the industrial society, I have told you that the family strides, if they are weak, today we see them being more weak. Life was fast, today when life is very fast, we will see these issues. This is why I told you that there are a lot of advanced countries in the population, you can't see them there now. In the coming few years, there will be no population there, there will be a lot of children's misdeeds, such highly industrial societies will have a lot of problems. We all know that countries are run by its people. Even whatever technology we are using, we still need people. Even we are making robots, we need people to make robots. If we are working on the artificial intelligence, we need people to work on artificial intelligence. Every country needs scientists, every country needs people to work on agriculture, every country needs industrialists, people from commerce and other sectors and doctors and everything. So these countries where we have seen so much development, because of the to catch the fast life speed. There are very few children's misdeeds, there are many countries in the world, there are bigger population dynamics, for those countries, they can be dangerous. However, if we go from this to 90 degrees, then why are your underdeveloped developing countries, especially the underdeveloped nations, are behind all these countries in 200-300 years of technology, you will see a lot of increase in the world. However, if the world stops, you won't be able to see it. In a few parts, you will see the problem where the world will not be able to see it, because of this post-industrial development. The information revolution is at the heart of the post-industrial societies and it is most evident in rich countries, yet new information technology affects people in all countries around the world. IT, it is a world of IT, it is a world of advanced technologies, that is also a very significant thing. So the worldwide flow of the products, products are coming from one place to another, and information, the flow of information, so today's world is a globalized world, and as I told you a little while ago, we will see the patterns and dynamics of the population in a little while.
