That seemed less than useful.<p>What do <i>people</i> answer when asked the question "what if my red is your blue?"<p>If any of them answer "That is impossible, red, green, and blue each exist as different wavelengths" then do we assume that they are not conscious? Or that the person has no visual qualia?<p>(Technically, the argument is "an AI lacking any visual qualia might respond with" so I'm committing logical fallacy. However, if many people with visual qualia give an answer that is consistent with what's assumed to be a lack of visual qualia then that answer is not diagnostic about the existence of visual qualia.)<p>Furthermore, color names are tied to culture. <a href="https://en.wikipedia.org/wiki/Color_term#Cultural_differences" rel="nofollow">https://en.wikipedia.org/wiki/Color_term#Cultural_difference...</a><p>Some languages don't have a word for green. For example, quoting from <a href="https://en.wikipedia.org/wiki/Himba_people#Color_perception" rel="nofollow">https://en.wikipedia.org/wiki/Himba_people#Color_perception</a> "The OvaHimba use four colour names: zuzu stands for dark shades of blue, red, green and purple; vapa is white and some shades of yellow; buru is some shades of green and blue; and dambu is some other shades of green, red and brown."<p>How do you even ask a question like “Could there be a color greener than green?” to someone from a culture which doesn't have color terms? Quoting <a href="https://en.wikipedia.org/wiki/Pirah%C3%A3_language#Color_terms" rel="nofollow">https://en.wikipedia.org/wiki/Pirah%C3%A3_language#Color_ter...</a> "There is also a claim that Pirahã lacks any unique color terminology, being one of the few cultures (mostly in the Amazon basin and New Guinea) that only have specific words for light and dark."<p>Does that make them any less conscious?<p>Finally, are any animals other than humans conscious? This argument seems to be that we can't tell if anything is conscious unless it speaks a human language.
