The reason for it is simply that ChatGPT is a consumer product.  The same people who condemn it for not taking controversial stands would condemn it much more loudly if it did \u2014 just like the same people who condemn it for wrong answers and explanations, would condemn it equally for right ones (Chomsky promises as much in the essay).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I submit that, like the Jesuit astronomers declining to look through Galileo\u2019s telescope, what Chomsky and his followers are ultimately angry at is reality itself, for having the temerity to offer something up that they didn\u2019t predict and that doesn\u2019t fit their worldview.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[<em>Note for people who might be visiting this blog for the first time:<\/em> I&#8217;m a CS professor at UT Austin, on leave for one year to work at OpenAI on the theoretical foundations of AI safety.
