It's still a little premature to make that prediction. This graph (http://upload.wikimedia.org/wikipedia/commons/a/a0/US_Crude_...) from that Wikipedia article shows a dead cat bounce. It's still too early to say whether that bounce will top the record production number in the 70's.
I just see it from the other point of view. I see it as being too early to say that he was wrong.
The article seems way too harsh on someone who made a prediction over 50 years ago that has stood the test of time flawlessly. He was objectively correct when looking at actual data.
The only counter point actually given in the article to peak oil is that it might be theoretically possible for production to beat those 1970's levels which isn't much of a counterpoint.
