I wish I had mod points. This. Exactly because this an issue of scientific method, dissenters should be (almost) welcome.

Maybe if you bought one you would know at least how to spell its name. It's “Britannica”, for your information.

4.3 sigma corresponds to a confidence level of 99,998292% (credit to Wolfram|alpha). This is about as certain as death and taxes if compared to “everyday” events, but maybe it's not enough for theoretical physicists (I'm not one).

What about “no trains because they spy me” but he's ok with planes?

While that may save your life in such a circumstance, if the cruise control fails to disengage, he won't be happy with the speed decreasing; I hope their feedback control is saner than the rest of the software, but you might end having the machine revving up like crazy by itself, still not good.

Does this mean they'll be releasing the source code?

The funny thing is, nobody with a Blackberry will get this joke.

You do raise a very interesting point, which would be worth discussing far more than my limited attention span and the hostility to long form writing of this input box allow me to.
I do think that the interest of OP goes beyond the superficial coverage of these topics we often see in press and politics, and this is already made evident by the fact he came here to ask. Moreover, even a cursory read of the Russel-Norvig brings no risk of misrepresentation - that's exactly why I loved that book: clear language, and only good information. I do think that a full-fledged, graduate level AI or game theory of soft computing course would be much more beneficial, but if he cannot invest that kind of resource, we can probably agree that he's better off with a great book than with some random snippets on wikipedia.

Seconded. There's everything you need, and it's also well written. No wonder it's a de facto standard in universities everywhere.

What TFA forgot to mention is that the attacker can change the password without breaking a sweat. So while still not straightforward (you have to get the user to execute your applet), there is no need to brute force.
