  "transcript": "Amazon bought a 960 megawatt nuclear reactor for AI servers. Microsoft restarted Three Mile Island. Stargate is spending 500 billion dollars on data centres. All of this to do, badly, what your brain does for free on the power of a dim light bulb.\n\nThe reason is that silicon processes information nothing like the brain does. Rigid chips with identical transistors trying to mimic something soft, three dimensional, constantly rewiring itself, with billions of different neurons each doing something slightly different.\n\nNorthwestern University just published research showing they printed artificial neurons from MoS2 and graphene ink that produced biologically realistic electrical spikes. They tested on living mouse brain cells. The brain responded as if the signal came from one of its own cells.\n\nThe breakthrough was accidental. Every other lab had been burning away the polymer residue left in the ink after printing. This team kept it. That residue created the switching behaviour that made the spikes biologically realistic.\n\nThe neuromorphic computing implications here seem significant. If you can print devices that process information the way neurons do at scale, the energy math changes completely.\n\n\n\n--- Top Comments ---\n\n\n[22 upvotes] What nonsense. Can your brain write a full video game in 90 seconds?\n\nCan your brain prove as-yet unproven mathematical theorems in the space of days?\n\nCan your brain take a PDF and condense its dense research mathematics into code that runs medical research machines in the space of a few minutes?\n\nYour brain might be able to do some of these things, but it can’t do any of these things at the speed of AI.\n\nWhen framing brain vs AI we must consider not just qualitative output, but the speed of those outputs. \n\nOur brains have been completely outclassed by the speed of AI, but that speed needs what you’re talking about at the top: power.\n\n[8 upvotes] Covered this in a [documentary](https://youtu.be/P76k0pysLQA) if anyone wants to go deeper on the mechanism and the computing implications.\n\n[8 upvotes] Bingo,   \nThinking and Consciousness as 'Neural Transistor' - Brain Cells.\n\nAs expected.\n\nCool.\n\n[6 upvotes] Machine learning is just pattern recognition and very much more efficient than us on that\n\n\nHuman intelligence is a lot more complex tho than just that",
