Re: That was a pretty short interview
Hyppönen is a legitimate security researcher ("guru" is rather strong, but then restraint is not a Reg strength). Though most of his actual research is in malware analysis, which is fine, but hardly groundbreaking. As far as I know he's never published substantial new research.
Mostly he gives a lot of keynotes and soundbites.
In any case, yeah, this is a pretty thin interview. "Here are some vague predictions. We're all doomed!"
