Chomsky basically says that intellectuals have a responsibility to expose the lies said by those in power. Hard to argue with, but maybe kind of a platitude.
I think I’d answer this question differently in 2026. The responsibility of intellectuals to society at large today, in an era overwhelmed with information, propaganda, immensely complex issues, etc. is – communicate the issues of the day in a way that is clear and accessible. With the assumption that intellectuals are “experts in ideas.”
I say this because so many contemporary debates seem really mangled and unclear, which makes them basically impossible to solve intellectually. Instead they just turn into battles of will where one side seeks to defeat the other in toto, not actually arrive at a solution that overcomes the conflict.
Unfortunately the academic system is explicitly designed to create specialists, not people that can effectively communicate to the Everyman.
