The flip-flopping of AI critics is completely explainable by flip-flopping morals of the architects.

> Dr. Hinton said that when people used to ask him how he could work on technology that was potentially dangerous, he would paraphrase Robert Oppenheimer, who led the U.S. effort to build the atomic bomb: “When you see something that is technically sweet, you go ahead and do it.”

If anyone outside the core architects changes their mind on AI either way, I don't think negatively at all. It's all confounded by the naivete of a few, which by definition is open to constant change. The critics just did or didn't think someone so naive could rise to so much power.
