Many unique jobs that are done now will be done by machines and robots in the future. Thus in the future
There will be more social instability and creativity-intensive jobs. Due to this there will be many changes and imbalances in the global economy. Untimely trees, suicides, illegal activities such as robbery and drug addiction will be rampant. Not only John, many researchers say this.

"A book does not give people food or clothing. But it gives them a clear knowledge to live in this world. Similarly, if this book gives clear knowledge and authority to discuss the future of man, then it is a great work."
- Yuval Noah Harari

Yuval has also mentioned many fields that can happen in the future. Some of them.

Information (information / data) is going to be the source of the world's greatest power in the future. To whom information is poured, he will be omnipotent and a superpower capable of ruling the world. Because information is shaping up to be the most powerful weapon of the future, they say. To put it more simply, let me remind you of the dialogue from the recently released movie 'Irumbuthira'. 'Information is Wealth' Arjun would say that if I had this data in my hands, I would be the crowned king of the digital world ruling the world. From ancient times till now, those who own more land (land/real estate) are said to be in power. Governments try to control them. But in the future whoever has the most data is going to be the one with the power.

Human Hacking - Human Hacking
We have heard about computer and machine hacking. Those who hack and steal like that are going to hack the human brain in the future. Can't believe it!?! Even if you don't believe it, that's the truth! They have already embarked on research to hack not only our systems, mobiles, bank accounts, social websites, digital devices, but also our brains and thoughts.

What changes are happening in our body, they have decided to hack our identification technology (biometric) and conquer people. If they do that, they will decide what we should do, what we think and what we should do. Even if it can't be brought about completely, researchers say that even with a 50% success rate, the extinction of the human race will be unstoppable.

Education - Education
Many jobs/jobs will disappear by 2040-50. Researchers say that all the subjects/syllabus taught to children in schools/colleges are likely to be ineffective. Until now, it was customary for man to spend his first 25-30 years in learning and use the remaining years to prepare himself for life in the world. But they say that by the time we finish studying and go to work, many of the things we have studied will be outdated information/studies/things. The only way to improve ourselves till the end of our life is to win in this competitive world and we should never stop learning. They say you should keep learning even at the age of 50. Although this is the case now, the situation will be even more competitive in the future.

They say that people should get used to living with emotional intelligence and mind balance.
