My take on it is that this post at Physics and Cake was simply a follow-up post to her talk at H+, which was itself also a forum intended for a broader audience within minimal time for any introductions of background material (which, from discussions with Suzanne, I know she is aware of). I would like to repeat that you should not rush to conclusions, but instead stay tuned.
Patently untrue. Suzanne is quite well aware of wireheading, the term, etc. Her investigation, of which only the beginning was mentioned in her post, concerns the broader problem of creating self-improving superintelligent general AI. Don't rush to conclusions, instead stay tuned.
Thank you, Alexander. :)
