Upgrade Culture

It is astonishing to think about how fast technology develops in our world today, when we consider that 100 years ago people had never heard of mobile phones. But will it ever stop? Will there ever be a time when we as a society decide that the technology we already have is enough for us in life?
We subconsciously know that every time we purchase a new phone, or up-grade an already perfectly good computer programme that another phone, ten times better than ours is being made and another computer programme has already been put into practice.
Is the reason behind this extreme up-grade culture, consumerism? Are up-grades designed for a money making purpose? We have become programmed to want the next best thing, to make sure that the programme for our computer is the fastest, most up-to-date programme around, and many people will pay a lot of money to make sure this happens.
I believe that as a technology reliant society we have come to expect upgrades, we know that within a matter of months or weeks something bigger and better will be available to us. Perhaps it is the greed of many of us which is causing this vast increase in upgrades. What would we do if suddenly the up-grades stopped, and we were forced to live with the technology we had at the time. Would we be able to accept what we have? I think that now we have seen the positive effects of 'up-grade culture' we will always be looking for more, 'up-grade culture' has become more than a money-making business, it has become a necessity for our technology reliant society.
