Ha cheers for the vote of confidence martin.
I think you're right that it's reasonably informed as such things go and could have been more blatantly wrong, but don't you find the whole slant of it - assuming that funky is already on the way out and that "funkstep" etc. = "the new thing" - a bit um dubious?
He says right near the beginning "Funky has never been weird, experimental music" and then goes on to single out Cooly G, Roska and Scratcha DVA as exceptions.
Massive props to those artists but this claim is just wrong, they're first among equals among heaps and heaps and heaps and heaps of artists. And I'm not talking about obscure producers only a scene DJ would have heard of. What about O.B., Madd.One, Scotty D, Swift Jay, Fuzzy Logick, D-Malice, Major Note$, Ill Blu, Mos' Wanted, even Crazy Cousinz - "Always Be Mine" is nearly as daring a production as anything Roska has done (and again, that's no disrespect to Roska!).
The only explanation for his slant is that he's wilfully ignoring anything without the official seal of approval of Rinse and Hyperdub (!), or he's simply ignorant of it, in which case he simply doesn't know the genre well enough to make the kind of sweeping judgments he's making.
