Peter Plantec, THE Peter Plantec, is a world renouned digital artist and software designer.  He authored several respected books, including Truspace 2 Bible, Virtual Humans, and is a contributing columnist at VFXWorld in Hollywood.  He's an authority on virtual human design and artificial intelligence.

I don't know if that post was really by him or not, but I'd be very surprised if he actually "stole" any content.  I don't see why he'd have to, other than for research on a book or perhaps anti-malware software design.
