If you read past the first sentence, it's quite obvious that the article is mostly concerned with claims of your type 2). Also I'm not sure why it would be so important to carefully separate the two categories of claims - they both rely on the assumption that AI can perform a wide variety of cognitive tasks better and cheaper than humans, which is addressed at length and cogently in the article.
