Does anyone know how to handle the depression/doom one feels with these updates? Yes, it's a great technical achievement, but I just worry for the future. We don't have good social safety nets, and we aren't close to UBI. It's difficult for me to see that happen unless something drastic changes. I'm also afraid of one company just having so much power. How does anyone compete?

Has anyone else noticed the leg swap in Tokyo video at 0:14. I guess we are past uncanny, but I do wonder if these small artifacts will always be present in generated content. Also begs the question, if more and more children are introduced to media from young age and they are fed more and more with generated content, will they be able to feel "uncanniness" or become completely blunt to it. There's definitely interes…

I noticed at the beginning that cars are driving on the right side of the road, but in Japan they drive on the left. The AI misses little details like that.

(I'm also not sure they've ever had a couple inches of snow on the ground while the cherry blossoms are in bloom in Tokyo, but I guess it's possible.)

This is very impressive. I know in general people are iffy about research benchmark. How does it work to evaluate text-to-video types of use cases? I want to have some intuition on how much this is better than other systems like pika quantatively.

I think the implications go much further than just the image/video considerations. This model shows a very good (albeit not perfect) understanding of the physics of objects and relationships between them. The announcement mentions this several times. The OpenAI blog post lists "Archeologists discover a generic plastic chair in the desert, excavating and dusting it with great care." as one of the "failed" cases. But t…

> very good... understanding of the physics of objects and relationships between them

I am always torn here. A real physics engine has a better "understanding" but I suspect that word applies to neither Sora nor a physics engine: https://www.wikipedia.org/wiki/Chinese_room

An understanding of physics would entail asking this generative network to invert gravity, change the density or energy output of something, or atypically reduce a coefficient of friction partway through a video. Perhaps Sora can handle these, but I suspect it is mimicking the usual world rather than understanding physics in any strong sense.

None of which is to say their accomplishment isn't impressive. Only that "understand" merits particularly careful use these days.

Does anyone else feel a sense of doom from these advancements? I'm definitely not a Luddite, I've been working professionally as a programmer for quite some time now, but I just can't shake this feeling. And this is not in the "I might lose my job to this" kind of feeling, that's obviously there, but it's something deeper, more sinister. I don't think I can explain it properly. Anyway, videos look incredible. I genui…

I think my thoughts went in a similarly sinister direction, when I saw it. I couldn't quiet grasp it.

My mood wasn't euphoric, to say the least.

This is insane. But I'm impressed most of all by the quality of motion . I've quite simply never seen convincing computer-generated motion before . Just look at the way the wooly mammoths connect with the ground, and their lumbering mass feels real. Motion-capture works fine because that's real motion, but every time people try to animate humans and animals, even in big-budget CGI movies, it's always ultimately obvio…

I disagree, just look at the legs of the woman in the first video. First she seems to be limping, than the legs rotate. The mammoth are totally uncanny for me as its both running and walking at the same time. Don't get me wrong, it is impressive. But I think many people will be very uncomfortable with such motion very quickly. Same story as the fingers before.

Agreed and these are the cherry picked examples of course.
