Not to take anything away from the Neuralink team, but predicting joint movements in a steady gait is one thing. Predicting join movements in starting, stopping, changing speed, and accurately manipulating objects is quite another.
- newsclues 6y agoPresumably they start with easy walking and build capabilities incrementally. The model to push impossible tech has worked... cars and rockets.
- refulgentis 6y agoThat's kind of the thing though...those took 26 bil in subsidies to generate 20 bil in revenue to duplicate existing tech (spacex def gets credit for reusable, obvi, but Tesla man, yuck)
- newsclues 6y agoI’m not sure about the numbers, was thinking about the model to progress technology rapidly. The reusable rocket tech seems worth it alone.
- PH01 6y agoNot to take anything away from the Neuralink team, but predicting joint movements and angles is about the edge case of what can be achieved with semi-invasive and non-invasive bci. Recording from the nerves predicting joint movements in a steady gait is definitely already achievable.
- lightgreen 6y agoIt can be predicted with the same precision/throughput, better than left/right:1/0 once per second? Can you share some link?
- PH01 6y agoWhat Neuralink present appears to be almost the same as this semi-invasive from 2013: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0072085 https://journals.plos.org/plosone/article?id=10.1371/journal... I am not up to speed on the non-invasive work, its called motion trajectory prediction (MTP) BCI. It is quite different from the method you decribed, which is a traditional motor imagey (MI) BCI.
- jfoster 6y agoIs your hypothesis that there is nothing they could do that would both be not too far from what they have now, plus valuable?
- kevinskii 6y agoI believe that Neuralink has potential to do great things. However, like many other Musk ventures, they vastly exaggerate their own accomplishments while downplaying remaining challenges. Most brain-machine interface advances will probably be made elsewhere.
- jfoster 6y agoI think that's just how progress gets made quickly. As Larry Page would say, "have a healthy disrespect for the impossible."
- runawaybottle 6y agoFor what they are trying to solve for initially, we’re talking about people that cannot even move a finger.
