I would like to continue a bit more on the scheme of technology and history. Just in terms of communications alone, for the past several millennia, letter writing has been the predominant mode of communication for most people. Email, instant and text messaging has changed all that.
Also, the democratization of knowledge with websites like wikipedia has meant that all the information in the world is at everyone’s fingertips. This has had innumerable side effects. It has changed the way people sell to one another. Back when ‘buyer beware’ was a common cautionary measure, information was not so freely available. Today’s salespeople have to come up with genuine reasons to sell based on the needs of clients. This has been noted by the author, Daniel Pink.
All the above factors have meant that in the post-industrial age, innovation, service and knowledge have become the cornerstones of the economy.
