"Is this a variant of what it is like to be a bat?"
Is there something that it is like to be you? There are also decent arguments that qualia does matter. It is hardly a settled matter. If anything, the philosophical consensus is that qualia is important.
"Whether some AI has qualia or not doesn't change any of the external behavior,"
Yes, behaviorism is a very attractive solution. But presumably what people want is a living conscious artificial mind and not a useful house maid in robot form. I can get that functionality right now.
If I write a program that allows my PC to speak in perfect English and in a perfectly human voice can my computer talk to me? Can it say hello? Yes it can, Can it greet me hello? No, it cannot because it cannot intend to say hello.
"Behaviorism as that word is classically defined isn't an attempt to explain consciousness."
Wikipedia? Really? Did you even bother to read the page or are you just pointing to something on wikipedia and believing that constitutes an argument? Look at section 5 "Behaviorism in philosophy". Read that and follow the link to the Philosophy of Mind article. Read that. You will discover that behaviorism was at one time thought to be a valid theory of mind. That all we needed to do to explain human behavior was to describe human behavior.
"If it is raining, Mr. Smith will use his umbrella. It is raining, therefore Mr. Smith will use his umbrella." Is this a valid deduction? No, it isn't because consciousness is not behavior only.
If you are a fan of Doctor Who, is the Teselecta conscious? Is there something that it is like to be the Teselecta? My answer is no, there is nothing it is like to be a robot piloted by miniature people emulating the behavior of a real conscious person.
Don't be a blockhead. ;)
Is there something that it is like to be you?
I'm not sure this question is any better formed. "What it is like to be an X" doesn't seem to have any coherent meaning when one presses people about what they actually are talking about.
If anything, the philosophical consensus is that qualia is important.
Taking qualia seriously as a question is a distinct claim than qualia actually having anything substantial to do with consciousness. I'm not sure of specific acceptance levels of qualia, but the fact is that a majority of philosophers either ...
