Comment Foccused ultrasound but yes. (Score 1) 37

microwave labotomy ... We just put the machine against your head here for a bit and those bad urges go away, all better.

Another poster mentioned that it's actually focussed ultrasound.

Still sounds like breaking a piece of a system by stirring the brain with a knife (lobotomy) or burning it out with heat (cauterization), electricity (electroshock) or mechanical shock (blow to the head) - just carefully focused without (substantial) damage to other parts of the brain or its casing.

Ultrasonic destruction of a piece of the brain's reward/punishment/desire/avoidance mechanism rather than persistent unwanted fat.

Yeah but the computer is running millions of move simulations, but a grandmaster is doing 1 millionth of that computation and still playing well. If we restricted the computer to only do a few thousand evaluations per second it would fail miserably. Same thing with self-driving a car. A human can learn with 20 hours of driving school, meanwhile the FSD training models need tens of billions of miles driven in simulation and all kinds of scenarios reasoned through for it.

We're missing some fundamental thing(s) when it comes to computation. I have no idea what it is -- we only know that there's a way to do it but we don't know how. Somebody, or AI itself will figure it out soon (like within a century, maybe even a decade or two).

Reminder of what I read in a magazine some decades ago, that the human brain utilizes just 25 to 50 watts and uses electric and chemical impulses while immersed in conductive fluid. When playing chess, a grandmaster can evaluate at best about 6 moves per second while a computer evaluates millions .. yet the computer is only two or three times better than a human.

I can figure out what hue, contrast, sharpness, and color saturation settings should be on my NTSC television. Anybody remember having to adjust that on a TV .. and the V-hold. Not to mention those rabbit ear antennas. Kids nowadays have it good, sort of. It was also fun now looking back.

Yeah because it's directed within a specific area. This is a range of emitters over a large area with a large amount of wave diffractions and interactions. I'm not saying it's unsafe. I don't know the energy levels involved or anything like that. Just that it's not necessarily safe, compared to say non-ionizing radiation or magnetic fields.

Comment 0.5 mm resolution (Score 4, Informative) 25

0.5 resolution is what a standard MRI provides. If it can do that and differentiate hard and soft tissue I will be impressed. The demo images they showed looked nowhere near the required accuracy. They still have a year to get it working I guess. Ultrasonic is very difficult given blood flow and all the associated movement with heart beating and all that. Also, they claim it is safe due to lack of radiation. But ultrasonic can fuck shit up too. I mean ultrasonic is currently used to break up kidney stones, shear and fragment DNA (for NGS prep).

Comment Tesla already perfected FSD (Score 1) 11

FSD has driven me hundreds of times consecutively so far, garage to congested city parking spots, with zero critical intervention on my Tesla. Not just me but look on YouTube etc. you'll see that with version 14 of FSD it's pretty much flawless -- it even handles drive-throughs .. cones/construction zones etc. I'm telling you it's at the point where I'm not sure what more they need to add -- other than accessory features like favorite parking spot memory, parking structure navigation. Someone said it can't see a chain across the road .. never encountered that I guess .. not sure a human could see that either? Note .. FSD is perfected, but Tesla's navigation .. which Google and even Apple solved 10 years ago.. sucks .. but that's because they are refusing to license Google for nav.
