What is 4th Industrial Revolution (4IR) and how will it affect us ?

The birth of technology and the Industrial revolution that followed has been one of the greatest contributions and reasons why the past 300 years of human life on planet earth has been very productive.

In these 300 years, to be more specific in the last 70 years, since the dawn of the Digital Revolution or birth of Digital Computers, humans are exploiting more natural resources, they are able to lead more productive lives, they are more healthy, they are economically more productive, they are able to explore unseen frontiers of the earth and beyond to moon and neighbouring planets and so on.

The population of the earth at different stages in human evolution over the past 2000 years is given in the below table.

If we look at these population figures, we find it is the 50 year stretch from 1950 to 2000 AD, where the impact of technology, medical technology and developments in medical science, invention of the Digital Computer etc that led to global population growing by 238% from 2557 million to 6094 million.

The increase in population from 2000 AD to 2050 AD is projected to be just 50% of the population in 2000 AD.
