Krebs is a charlatan like many others. I don’t know why he’s given so much clout in technical circles. At this point he’s nothing more than a journalist.
Journalists are all charlatans since for the most part they know very little of what they’re talking about. “Journalist” is practically an insult at this point.
Of course, I may be a little too sensitive about this kind of stuff. I am in the middle of reading Neal Stephenson's REAMDE right now.
