The promise is significantly reduced device costs for far superior electrode counts. Even if it can't interpret yet, the ability to get a more nuanced look at the firing of neurons should be a huge benefit to help increase understanding

Haven't really looked into it, but the big demo where the pig would walk on the treadmill and the model tracked its movement really set off my bullshit radar (high signal strength of muscle actuation, cyclical nature of the signal - it's not at all what you'd show to convince someone who was familiar with the literature that it's not just more bullshit snake oil).

The monkey playing the computer game was the more interesting one imo - but it’s outside of my field of expertise.
