If you happen to know a little computer and Internet programming (not Bitcoin programming here), you can make the already very strong encryption of the secured sections of the Internet to be even stronger. It doesn't take much.

The point is, that without a whole lot of additional programming, Bitcoin can be made a bazillion times more secure than it already is. And then that security can be adapted to all kinds of things - emails, phone conversations, text messaging, etc. - so that almost nobody can know who is communicating and transacting with whom, if they so desire.

The technology to do this is here right now, and has been for a long time. There just hasn't really been a perceived need up until now.
