Two things:
1. - I have trouble believing anything connected to the Internet is safe and secure, especially from someone who knows what they're doing and wants to access it. Hmmm, ya know... If they didn't know it was there, it would be a non-issue, wouldn't it? Maybe I'm onto something there! On the other hand, how do you hide anything online? There's encryption, but that doesn't really 'hide' anything. Hmmm.... Anyway, what was I saying? Oh yes! Anything and everything on the Internet should be considered public, which is why you should be careful what you say online. Anything said anywhere online is equivalent to being published in a newspaper, and may even be brought as evidence against you in court. This is a fact that one should always keep in mind. Also, with talk of even high ranking military security being hacked, such as the Pentagon, it becomes evident that there is no such thing as security online, either. The best you could hope to do would be the same thing you do when locking up your bicycle: Buy more time, in hopes the thief will look for an easier target.
2. - I don't know for sure if it's true, but in the days leading up to the activation of the Hadron Supercollider in Switzerland, the rumors I heard were saying that if it were to malfunction and get out of control, it could lead to the destruction of the entire planet. Some of the other things scientists are tinkering with give me the heebie-geebies: Like trying to open a door into other dimensions, or finding out the limits of physicality, taking things past absolute zero, for instance. They've already made things like a liquid that can go through a solid. What next? What happens if they open a door and something comes through that can't be stopped? Yeah, I know it sounds ludicrous, and like something from a bad horror movie, but the point is: Shouldn't we be a lot more cautious when poking around in areas no-one's ever been before, and which we have no way of knowing the results of our prodding?
Just sayin'....
