Give me a break. Would you mind sharing what makes you more qualified than the author to "observe consciousness" and come to conclusions regarding the requirement of memory? I'd say it's a "red flag" when a game designer on hacker news throws out unsubstantiated attacks on an extensive well-written rational analysis about the physical manifestation of consciousness by a prominent MIT physics professor and cosmologist.
Additionally, I think you are quite clearly wrong. Consciousness does require memory. It is not possible to observe, experience, or process without memory, all of which are required for the integration of consciousness. Even to perceive requires memory, since it requires the integration, filtering, and processing of large amounts data into consistent perception and a conscious interpretation thereof - none of which is instantaneous and all of which takes time, requiring memory.
