The standard for youtube has always been to never read the comments, now that he mentions it, they really seem better now. In a follow-up he mentions the downside, now most of the comments are people saying they love the video.

That's... a lot of movement right?

I suspect this kind of household robot is still a bit far off, but the way they trained this one is really interesting. They have a rig that can be set up with it so that a person can operate it like a mech to train it on what the task is supposed to look like. They found this kind of training was more effective than expected. Also impressive: they put this thing togther for $20k. It's just a laptop with a mobile 3070ti. Also check out the video of it making horrible mistakes.

I had not realized that the standard is 90 seconds, but what I have read in the past is that the biggest danger is suffocation, especially because jet fuel fumes are pretty toxic.
Longer Reads
• Short thread discussing The Truly Disadvantaged by William Julius Wilson. One tidbit: discussion of why black neighborhoods got worse in the post-civil rights era.
• A thread of famous paintings recreated as photographs with midjourney. When I saw it I thought 1) that it was pretty cheasy, and 2) that it would be pretty easy to do. So I gave it a shot, and blew half an hour and couldn't get any of them as good as I wanted using Midjourney alone.
I really didn’t like their Jatte or Wave, but to do better I think I’d need to bring thees into Photoshop. The hardest part is actually getting the overall parts of the picture to be in the right place and to be the right size. And don’t even try to ask Midjourney for Mt Fuji anywhere in The Wave, because if it hears “Fuji” it’s instantly the whole image.
