From a computational point of view, consciousness is just another ingredient in the chain of cause-effect relationships of a deterministic physicalist universe.
Meaning is central to computation.
If by 'computation' we mean the act of someone using a computer to perform some symbol manipulation or calculation, then I would be able to agree with this last statement because then the computation is meaningful to the human user. Computation might be characterised as a science of how physical systems can display, utilise and be influenced by the meanings of symbols. Machines like computers do what they do because they have no other choice in the matter, and not because it is meaningful to them. A thermometer displays the temperature because mercury expands when heated and not because the amount of agitation of the air molecules in the room is a symbol which the thermometer interprets as meaning it should then find the number on the scale to match. This is precisely why I find it such a uniquely suggestive metaphor for mental activity.
