Farhad Manjoo at the New York Times wrote a good piece on the future of Bitcoin and potential ways to make it more secure. Worth a read.
One frequent analogy in the Bitcoin world is to the early days of the Internet and web. Just a decade and a half ago, the web was a rough-and-tumble network ruled by pornography and illegal file-trading, a place where fraud flourished and danger lurked around every corner. Today the web is still all that, but it is also, in its more respectable corners, the place where you post pictures of your children, where you shop for Christmas presents, where you hold secure conversations with your doctor and where companies make billions of dollars every year without worry of being defrauded.
