The demo was impressive. Did the author not see the part where they were predicting the body position of the walking pig?

I don't see how that is going to be done with stick on sensors.

And yes, some implantable BCI devices have better capability. The point is to make this as cheap as possible... so that it doesn't require a brain surgeon to install. Because brain surgeons are expensive.

They start with animal tests, then impaired people and finally public at large. It's stupid to get implanted with a work-in-progress device yet, except if your life quality requires it.
