Now you would think that when you say something is complete, there is no requirement for anything else to add to it. So where does this question of enhancement come from? So you get yourself a microwave oven and it is more complete. And a year back it was more complete because it had a refrigerator with an inbuilt stabilizer. So what is complete? We define something as complete today and the next day that definition changes because we feel there's something we missed out. In the medical world every year or the second we have a new set of guidelines for our treatment protocols. What seemed good enough yesterday is good no more. We always have something better. Its not like we cannot live with what was complete yesterday but there is always this urge to have something better. This urge on which the capitalistic world lives on and the marketing world feeds on. So what is the lifespan of something that is complete today? The speed at which technology is upgrading itself will decide the pace of the change in the definition of completeness. There are upgrades for almost everything ... that's when you think its complete. - for now at least!
Thank God when we say we have a complete family, we do not look for upgrades for our parents or children (siblings maybe). Imagine Dad 2.0 , Mom 5.0, Sis 3.0 and Bro 7.0 in your family ... watchout for that day! That's going to be some complete family ... ain't it?
