The growth shown by human beings in last two centuries is unprecedented and beyond imagination. For reference, let us take a data of life expectancy into account. The average life of a human being in the year 1835 was below 35 years. 94% human beings were extremely poor and struggled to manage two meals a days for their families. Now if we compare this data today, only 10-15% people are living in poverty and average life span has reached 70 years. More than 80% human beings have the basic education. There is only one thing that has transformed it all, and it is technology.
