I'm sure there are unwarranted attacks on Stephen Wolfram out there in the public discourse, but what I see is people criticizing his ideas, which is always fair game.

I actually think criticism is especially important in the case of high-profile public figures like Wolfram. Far more people in the general public know about him and his highly speculative and unproven theories, while at the same time thousands of serious scientists publishing important and influential work go relatively unrecognized.
