There is currently no reason to believe that such a superintelligence is likely or would have any of the powers people claim.

There is no reason to assume that super intelligent evil AI with magic powers will appear; while we are purely in the realm of (hackneyed) fantasy, why stop at imagining just one thing? You can build the whole story, not just the basilisk.
The parent comment is a story, not a prediction; it should be treated like one.
