alt Hacker NewsAn underappreciated source of nonsense in 21st century discourse is people watching YouTube instead of reading things. It doesn't appear this author read anything, preferring to be spooked and misled by a YouTube video.
trained them to play DOOM - honestly better than I do.
>> While the neurons can play the game better than a randomly firing player, they’re not very good. “Right now, the cells play a lot like a beginner who’s never seen a computer—and in all fairness, they haven’t,” Brett Kagan, chief scientific officer at Cortical Labs, says in the video. “But they show evidence that they can seek out enemies, they can shoot, they can spin. And while they die a lot, they are learning.” [https://www.smithsonianmag.com/smart-news/a-clump-of-human-b... ]
To play DOOM, the system feeds visual data to the neurons. For the neurons to react, they have to interpret that data in some way.
>> So how does a petri dish of brain cells play Doom when it doesn’t have any eyes? Or fingers? "We take a snapshot of the game with information like the player’s health and the position of enemies, pass it through a neural network, convert it into numbers, and send the data,” explains Cole. “This is called encoding – essentially turning the game state into signals the neurons can understand. The neurons then fire an output – move left, move right, walk forward, shoot or not shoot – which the system decodes and converts back into actions in the game."

I am also concerned about neuronal computing. But it doesn't really help anyone to spread childish ghost stories about it.
I really hate YouTube, by the way. My dad used to read newspapers and had interesting ideas. Now he watches a bunch of YouTube and he's a huge idiot. It's not (directly) because of age: nobody is immune to narcotic slop. I had to delete my account when I realized how much of my life and cognition I was wasting. I wish others would do the same.

I really do suck at DOOM - and I did read the paper about BNNs, so I anticipated how it works, doesn't make it any less interesting [0]
Playing DOOM is playing DOOM - if it's through your keyboard or mouse of progressing through the game states to move forward - hope that makes sense.
I don't think the average YouTube influencer is growing 200,000 human neurons.
This did have some real scientific backing. Even if the 'result's are hyped.
It is little extreme to call this false because it appeared on YouTube.
Converting an image to numbers, doesn't automatically scream, this isn't seeing.
The brain does a lot of manipulation of the input images, the pixels from the retina, that doesn't sound far from just linear algebra.
I feel that "YouTube makes you an idiot" is a misdiagnosis. And one I hear frequently.
Books can make you an idiot too- I think of "Rich Dad, Poor Dad" or "Grit" or any number of pseudo-science best seller books. These books end up capturing the public imagination in big ways too- Grit caused some government policy in the US around when it was popular.
The difference, I suppose, is that YouTube works faster by having many different people presenting the same bad ideas that the algorithm has helped you to buy into.
On the other hand there are amazing and useful YouTube channels that I use all the time like Practical Engineering, Crafsman, Technology Connections, Park Tools, SciShow, Crash Course, and on and on.
