I just finished reading Simon Singh’s The Code Book, and I got the impression that PGP was basically uncrackable, and more or less always will be. However, the book was written 20 years ago, so, is this still true?

I don’t think there are any known serious attacks on PGP it self, but PGP is more “a practical way of using asymmetric encryption”. It has to use some form of asymmetric encryption (e.g. RSA) to share secret keys – and the security of PGP can therefor never be stronger than the encryption used here.
Usually when someone says “perfect security” it means that even with infinite computing power, you could never decrypt the message. Which is not the case for something like RSA – but we still believe it to be infeasible to break in practice for now.
