Reading about a Google Research project that generates videos of objects bumping into each other. I thought, cool, this is cute for like, making random weird vids!

Then I read the attached section on why they made it in the first place

Folks, they are trying to make up for the lack of ground truth video of physical object interaction by *simulating those interactions and training the AI on the simulation*

@darius on the other hand, if they did it right and set up a Laboratory For Throwing Actual Things At Other Things, I would apply for a Things-Thrower job immediately

@ranjit that's the thing. You could literally happily employ so many people but instead you feed fake data to a machine

@darius i wonder if there are already engineers out there trying to make materials that look and feel more like they do in video games (and other uses of physics simulation engines), so that those materials come across as more "natural" to consumers

@darius What if the real mechanical turk was the biased training set we made along the way?

@darius if it works you get a faster simulator, and you can hopefully use it on top of other techniques (differentiable rendering and/or differentiable physics simulation) to get a model able to work with real data. It's not that stupid, but it has to be used carefully

@darius there was a project called deepdrive which trained self driving ai on GTA IV. I think they were collaborating with tesla (lol). Horrifying!
