Automation is good or Bad

Will automation be good or bad for people's lives in the future?It's a very big question which is going on every where . See automation means creating something which make our life easier .Around 200-300 years ago , when a king required to send any message to another king he used to send a messenger, slowly we got post man who can pick letters for all and can drop. But now we have email , watsapp ,Facebook , so do you think that messengers and post man lost their jobs ?No , Now Facebook ,Gmail ,and WatsApp created lakhs of jobs,Internet based company provides lots of Jobs . So basically what happens here our requirement increased now every one need faster services so more people are their who need services.  We can send mail to any one in 1 second . Now what that person will do who used to worked as post man , he will find another job , may be he can start his own cyber cafe or he can start doing job in Internet technology , but he need to upgrade.In the same way .Now suppose you hired a person for sending mail to your clients and business partners , so tomorrow we will get another kind of automated tool which will automatically send mail to every one on a scheduled time . So here another person is losing job . So all I wanted to tell you automation is good it makes our life better and faster ,but again it depends on the level of automation. If it's in line with what we've seen historically, and see today, it won't have a lot of an effect. But there area a couple of areas that change that paradigm . Let me tell you few more examples . You have seen camera man in old days , they used to take pictures and we keep safe those pictures . In todays world still camera man exists , but they make pictures more beautiful so jobs never less ,always there another jobs.Many peoples are living in fear that  automation can kill jobs , But it generates another kind of skilled jobs with better possibility. If you asked grand father or Father, what problem they used to faced to withdraw money from banks by standing in queue ,At the current time you simply go to ATM and withdraw your money. Automation definitely makes jobs complex jobs simpler and faster so the total produce in a country will increase. Because of more available goods and less manpower required, chances are that the price of goods produced will be cheaper. But in the long run, I'm not sure if our economy can do well with less jobs.Please read clearly and give your comment on this issue.
