When you want to discuss "the myth of a superhuman AI", it's important to carefully separate the two categories of claims:
1. The claims by economists that AI-- even if it's not "strong AI"-- will put lots of people out of a job with potentially severe societal/economic repercussions
2. The claims by the Bostrom/Yudkowsky/etc. crowd that an AI intelligence explosion will cause the extinction of humanity
Without saying anything about the plausibility or lack thereof of either 1 or 2, I think we can all agree that they are very different claims and need to be analyzed separately. Right from the very first sentence the author seems to muddle the two, so I don't think there's much of cogent analysis in here.
