I only said he didn't know "some of the basics". Also, this is neither a personal attack on irrelevant facets of him, nor is it just about TCO. Python has done very well in its history and I personally like it. However, Guido made his final decision literally days after learning the distinction. This means before that any decisions he made in this area were based on shaky information. Furthermore, he was initially informed by comments on his blog, not his own research. I'm worried what this means for future decisions in Python if Guido doesn't research something on his own before making decisions on it. I understand that he's busy, but working of Python is part of that and surely research should be included :).
