Does "the investor challenged a room full of doctors to disagree with his argument" mean "the investor challenged all doctors in the room: if you think my argument does not hold water, please disagree with me and provide your own argument"?

Context:

Khosla, who wrote an article entitled Do We Need Doctors Or Algorithms? earlier this year, made the controversial remarks at the Health Innovation Summit in San Francisco, hosted by seed accelerator Rock Health. The article had already touched on some of the points of his keynote speech, however it was at the summit that the investor challenged a room full of doctors to disagree with his argument -- a challenge that was met with silence. Either the collection of professionals -- that included fellow speakers Andy Grove, Intel's former CEO, and Thomas Goetz, executive editor of Wired US -- were too horrified by a future where patient care is sacrificed for efficiency, or maybe, just maybe, they realised Khosla was speaking a lot of sense and that the healthcare system in its current state will, one day soon, be rendered redundant.
