No, it's pretty obvious what Nathan Myhrvold is up to.
First, he tried selling a cookbook. Thing is, though, he couldn't just write a cookbook... it had to be a huge, bloated, absurdly over-priced cookbook.
Now he's trying to get known as a science critic/gadfly. Unfortunately it's obvious he knows very little about the science, and is only getting press because of his name.
Nathan is known to the world for exactly one thing - the patent troll firm Intellectual Ventures. He has figured out that, if he's remembered by history at all, it'll be for that... and he desperately is searching for something, ANYTHING, that will somehow erase that huge taint on what he sees as his legacy. But it's too late, Nathan - you made this (patent pending) bed, now you have to sleep in it.
