The definition we favour is a lowest common denominator approach, based on affirmative ostension. Put simply, phenomenal consciousness is the feature(s) shared across all states which you've been aware of, whether those states involve cognition, sensations, dreams, transcendent experiences, or anything else. We can never know anything or experience anything except through a state of consciousness. The more states you can experience and rigorously analyse, the closer you'll get to the reality behind this definition, but most adult humans should be able to operationalise this approach adequately to support a practical dialogue. With language, as with any other tools we use to analyse the world or communicate, the requirement is a good enough working approach to make progress, rather than a perfect solution beyond any nit-picking.

this would be unthinkable to most software people whose instinct is to record everything everywhere never mind the cloud costs, because we are sure there will be some use for it later and some model to be trained later. i don't have a prescription here per se my point is just that our civilization routinely hoards and treasures some of the silliest data in the world "i pressed like on the john pork reel" & destroys much of all the most important data it generates and limits what machines can learn
