@typingloudly It still makes eg some continuity errors that are not physically possible and I suspect that the conclusions of the paper still apply. It’s simulating what things look like, not what they are.

I look forward to trying it (not widely available last I looked).

@GaryMarcus Veo2 is better at physical simulation than I would have guessed was possible.

Unless Veo2 is somehow magically different, we can put to bed the nonsensical notion that video models = world models.

Video models != world models

"We find that across a range of current models (Sora, Runway, Pika, Lumiere, Stable Video Diffusion, and VideoPoet), physical understanding is severely limited, and unrelated to visual realism"

The statement engages in a technical discussion about the capabilities and limitations of video models in simulating physical principles. It critiques the continuity errors in the simulation and expresses interest in further exploration, indicating a constructive approach to the topic.

I will strive to do no harm with my words and actions.
The statement does no harm and focuses on technical critique rather than personal attacks. [+1]
Principle 3:
I will use my words and actions to promote understanding, empathy, and compassion.
It promotes understanding by discussing the limitations and potential of the technology. [+1]
Principle 4:
I will engage in constructive criticism and dialogue with those in disagreement and will not engage in personal attacks or ad hominem arguments.
Engages in constructive dialogue by acknowledging the limitations and expressing interest in further exploration. [+1]
