I think the point 2 will rub many people the wrong way (me included) though. That would make reading Fourth Wing or Twilight a more connecting experience than most classics. (Nothing inherently wrong with that, but... you know...)

The classics were classic because they were the most available and the most popular stories of their time, and they meant more in an era where creating and disseminating media was difficult. I love to romanticize a world where we go back to the classics to connect with our past and present better, even if just for the sake of efficiency. For better or for worse media is more ephemeral which means getting to a common…

The thing is that literature, and art in general, should be more than just entertainment. It should edify the reader, communicate some concept, moral lesson or keen insight about the world.

Remember when you were taught to extract the "moral of the story" in school? That was the whole point. That form of communication is what makes art valuable and it definitely is what makes some art more valuable than others.

That's interesting, but how many people are actually going to just scroll and watch these (thereby generating ad revenue)?

They don't have ads, it's paid members only. You can see other people's images, including the prompts, so it's an interesting way to learn what works, and to mutate prompts and images. There are many ways of recombining or breeding images. They have an onboarding flow where you rate images and it tunes into your aesthetic preferences. You can create mood boards for specific projects. So I would say it's more communit…

Yeah, and definitely not AITok

Since when have to install Gemini? I’ve been using it via the web

A surprisingly large number of people use only installable apps. It's a crazy world out there.

Most people in the world only have a phone, no computer. Their window to software is the App Store or Play Store.

I know from a dev bootcamp that you are certainly wrong. However, I also think ai coding is hyped way beyond its capability.

I think you're overestimating how much power LLMs consume. Let's say one video pegs a top of the line Blackwell chip at 100% utilization for 10 minutes. I think a Blackwell chip (plus cooling and other data center overhead) is somewhere around 3000 watts when running 100%. So that's about 0.5 kilowatt-hours. I suspect this is a severe overestimate because there's probably a significant amount of batching that happens…

> It seems not unlikely that the amount of energy it takes to produce, edit, and process a TikTok video exceeds half a kilowatt-hour. That would be really remarkable, considering the total power capacity of a phone battery is in the neighborhood of 0.015 kWh

Yeah I should clarify. This is a very vague estimate around "total energy spent for making a video you wouldn't otherwise do" which includes stuff like lighting, transportation, video transcoding on the server, script writing, actor coordination, etc. E.g. if someone drives somewhere solely to make a video they otherwise wouldn't, then it gets included.

I hedged as "not unlikely" because I'd need to think harder about the amortization of more energy expensive videos vs less energy expensive ones and how much energy you can actually attribute to a video vs the video solely being an activity that would be an add-on to something that would happen anyways.

But it's not just the energy expenditure of a phone.

(I also think that 0.5 kilowatt-hours is an overestimate of energy expenditure by potentially up to two orders of magnitude depending on how much batching is done, but my original comment did say 0.5 kWh).

I think that short film is AI generated. I only watched like 30 seconds of an office scene in the middle but it spontaneously changed from daytime to nighttime with zero explanation.

He says it's not: https:/x.com/jasonjoyride/status/1973164183798816773

>> How do you get HD renders? im getting like super low res shit

>It's because this isn't AI

I haven't watched the film, but the premise is something about an orbiting space station. I could easily imagine scenes featuring rapid day/night cycles like astronauts experience on the ISS.

It’s not a good thing, but it’s definitely a thing. Most of us here on HN are going to be affected by this.

How many more years do you think you'll need to keep saying this before it's actually true?

New grads are already having a tough time. My own expectation is that every recession or downturn from here on out, there will be the typical rounds of layoffs but without the typical increase in hiring afterwards. Maybe no “we replaced you with AI” moment, more of a “no new hiring” tendency.

This is not the final target. It's video generation now, but that's just a stepping stone. The real thing is that learning a generator is also learning a prior over videos, and hence over how the world works. The real application of this will be word models, vision-language action models, spatial AI and robotics. Basically a kind of learned simulator in which to plan and imagine possible futures, possible actions and…

I think generally I agree with you that this is a stepping stone towards bigger/potentially more important things......but that doesn't change the fact that they've packaged it to consumers as something that seems like it has, at best, close to zero utility and at worst has incredible downsides. I'm not sure why releasing this to consumers helps achieve those goals.

Ad money to recoup the huge investments into datacenters that will do the training of the better models that do the things I mentioned. Meta is working hard on AR, glasses (project Aria), egocentric modeling and spatial AI. At some point they may also pull out the Metaverse idea too, they are still working on avatars too, it's just currently not so popularly hyped.

You didn't include the amortized cost of a Blackwell GPU, which is an order of magnitude larger expense than electricity.

Yeah that's fair (although the original comment was only talking about energy costs).

But this is kind of a worst case cost analysis. I fully expect that the average non-pro Sora 2 video has one to two orders of magnitude less GPU utilization than I listed here (because I think those video tokens are probably generated at a batch size of ~100 per batch).

Yes the tech is amazing. But tech is not everything, after 20 years of social media, its pretty clear to everyone that those things can have large long term impact both positive and negative for society, discussing the potential impacts of the tech is not being "political", its just being interested in the future.

Im not sure, what if society only learns through hardships?

Well certainly if you don’t want us to discuss the possible implications ahead, then yes we can only close our eyes and learn from hardship once it’s there, but then what do we learn ? To not close our eyes next time ? We could just do that like now.
