The question is whether phenomenal consciousness (that which involves qualia) has any practical utility.

Can you explain how we'd do any planning without consciousness? No self-awareness, no awareness of the future, no planning for any self in any future.

If you write code using complicated nestings of conditional statements (if/else statements), you have pretty much built something artificial that can do something akin to planning/decision-making (at least in the rudimentary sense) without the need for any qualia whatsoever. So it seems to me, then, that it is possible for an organism like the human being to plan ahead without any "inner movie running in their head".

Pain is little more than a damage indicator. Don't do this, it hurts. About as complicated as a check engine light. There's some pretty obvious survival advantage to avoiding an unnecessarily punctured hide.

And if pain is DMitry's bar for qualia then he's just thrown humanish p-zombies out the window. Every organism down to and including single-celled organisms exhibit some level of distress when damaged. It's about as fundamental a reaction as you can find.

Yeah, but there is also the feeling of pain as well. That is what Dmitry is referring to, not the outward behavior exhibiting it (or the activities in the nervous system that lead to it), but the inner subjective feeling of it.

And yeah, hypothetically, you could have p-zombie versions of dogs and other non-human animals that we believe have consciousness. It's not just humans beings that have phenomenal consciousness, of course. But I don't know if something like a bacterium would have that. Seems like ultimately, it's connected to the brain (at least in the case of living organisms on earth), and bacteria don't have brains.

The obvious issue is comparing humans to computers.

One has sentience, the other doesn't.

How is catching an object NOT a subjective experience?

I don't understand your question. Catching an object is external behavior.

External to what? Certainly not to the individual doing the catching.

I mean, Boru is not wrong here. From what you posted, it seems like they are unable to have subjective experiences involving vision, but they could still have subjective experiences in other ways. For example, they could still hear, feel pain, etc.

But as for your point, yeah I agree it lends support to what you've been saying.
