As I understand it, it has been an interesting connumdrum of artificial intelligence studies that it is far harder to get a computer to do something along the lines of 'tie your shoelaces' than it is to program a computer to dispense legal or medical advice. I don't know much about sonnets, but my hubby once wrote a very simple program to compose Haikus. Some were quite delightful. But he wasn't claiming that the program composing the poetry conscious. It was just a simple algorithm that combined random words from various lists in a specified order that met specified criteria.
Anyway, my point is that I find it quite believable that the process of eating lunch might be more representative of consciousness than composing poetry, particularly if 'eating lunch' includes such things as deciding what to eat, obtaining the ingrediants, preparing it ahead of time, etc. and is not referring to just the actions of fork picking up food, delivering to mouth and chewing.
