Use your imagination. Any event that cannot be defined by low dimensional meaning (which there are myriad). The problem with the distinctions between event perception (what causes a car crash) and what AI assimilates is the arbitrary bottleneck of words, causal statements, images, deep reductions which are possible illusions of semantics like beliefs, motivations, desires.
Humans can take in a remarkable array of stimuli in order to perform tasks that are not cause and effect through optic flow. AI is stuck behind a veil of predicted tokens.
In essence, AI cannot automate mimicry of understanding even when the magic act demonstrates. Events are already tapeworms, but our skillset is so stuck behind the veil of folk psychology and f science, we are merely pretending we understand these events.
So a tapeworm format is probably somewhat like a non-causal contradictory event that may have infinite semantic readings. Think edges of paradox: Kubrick, Escher, Cezanne, Giorgione, Song Dynasty landscapes, Heraclitus, find the Koanic paradoxes of the East and keep conjoining them. Think beyond words, as thoughts are wordless, the tapeworms are out there, math doesn't and can't see them.
This is what's so jarring about meme-culture, which are tapeworms to AI as they are tapeworms to narrative containment culture, what might be viewed as academia/intelligensia/CS engineering/plain English media, the tapeworms are here, CS I think assumes the causal/semantic linkages are simple, meaning is low-bandwidth, but the reality is semantic is both limitless (any event) and illusory (meme-culture ie several memes in sequence). AI has no path in either case.
