Why do people care who Satoshi Nakamoto is/was? It's like wondering the name of the person that created the wheel. Sure, I suppose I would be curious about the name of the inventor of the wheel, if nothing else to raise a beer to them from time to time, but ultimately the wheel is the important part of the story.
In my opinion not all people care too much who really Satoshi is. But of course in most cases people are interested in the invention mostly, and in the personality may be they are just curious and that is all. Banal curiosity. Those who are interested mostly in the Bitcoin and its nature and future destiny they do not care about the real or fake personality of Satoshi. And in case using a wheel every day a person do not even remember the name of its creator. The same is with Bitcoin and Nakamoto.
All care to the point that why he or they gone without tracks for over the years also people are so interested to know on whats current life status of bitcoin creator. Maybe there are other who just like the technology but majority is seeking the information about him/her thats why there are so many scattered fake information about him and its always posted on the news because whenever someone says they are Satoshi many people will get curious to see if he is the creator.
just out of curiosity only. people are curious who is satoshi. that's all. human beings like to know some personal stuffs of another person esp those who are living mysteriously and left a very vital mark to humanity. people will not stop to look for satoshi. more conspiracy theories on the table.
remember last year, even McAfee said he is 99% certain who Satoshi is ... lol
