"...there aren’t hundreds of thousands of people who want to take over the lives of my children, and those who want to make them have sex with farm animals (and other even odder stuff that happens in fan fiction) get sent to jail;..."Although, I cannot validate his concern, it reminds me of what happened in Ted Chiang's "The Lifecycle of Software Objects". This story was nominated for a Hugo this year and the central promise are AIs created by a company that slowly learn and live inside a virtual environment. However, hackers break into the system at one point and make clones of the software objects and these are used by even more questionable groups in obscene manners. Effectively, resulting in clones of the software objects undergoing the same thing that's talked about in Edmund Schubert's argument above.
I would have posted the above comments on the Magical Words blog, but I tend to read blogs after their freshness date expires. Dean Smith uses the metaphor of produce to describe the book industry. Whether or not that is a valid analogy, the same idea applies to blogs. Although, posts exist on them forever -- at least until the author deletes them --, conversations only occur while the post is fresh.
I could force myself to read blogs every day and if I don't get to them a certain day, don't read articles published that day, but I'm not willing to skip to the front of the queue, and I'd rather read the articles on my time instead of when they were published.
