It's because they don't have a substantive response to it, so they resort to ad hominems.

I've worked extensively in the AI space, and believe that it is extremely useful, but these weird claims (even from people I respect a lot) that "something big and mysterious is happening, I just can't show you yet!" set of my alarms.

When sensible questions are met with ad hominems by supporters it further sets of alarm bells.
