I really don't understand where GP's comment comes from...you don't even need to look her up; Robin Murphy's byline in the article itself makes it clear that she is a CS professor who directs a center for robotics. How could you possibly compare somebody with that set of credentials commenting on robotics to a "physicist speaking on literature or history"? As someone who's typically a bit skeptical of such allegations, the only explanation for GP's comment I can come up with is sexism... (But I'd be interested to hear any more charitable interpretations or an explanation from the comment's author -- I'm really pretty baffled by the comment.)
...what? She is a professor of CS & Engineering according to the byline in the article, and upon Googling her, I find no reference to her teaching economics or any other non-CS/Engineering discipline elsewhere. And unless ctrl+f is failing me, "econ" isn't mentioned anywhere in the article (except "economically" once in someone else's comment) or in this comment thread. So I have no idea what you're talking about.
She talks about econ and, as you diligently pointed out, that's not her area of expertise, exactly. OTOH I would assume that a professional does have a clue about adjacent topics.
