It may not be exactly clear where a temperature becomes 'hot', but the sun is still not a great place to host your wedding. If I ask a designer for black text on a white page and they come back with gray text on a gray page, nobody is going to be able to read it. My complaint to the designer or the head of tourism on the sun is not a semantic one, it has very real implications beyond linguistic.
I disagree that consciousness is along the axis of intelligence and awareness. My computer is aware of a thousand services and is smart enough to allocate resources to each of them and perform billions of mathematical operations in a second. My cat thinks his tail is a snake sometimes, and has never performed so much as an addition. But my best guess is that the cat is the conscious one. I expect you can produce qualia with no intelligence or awareness at all.
