I don’t mean to backseat engineer, but ensuring your BRAIN INTERFACE DEVICE succsessfully connects seems pretty fucking vital and worth of a redesign. Even if its expensive. Even if the probability is low, it needs to be virtually zero.
Its hard to take a step back and view this as regular product development that has timelines and such strictly due to the nature of the product. This is almost literally the most invasive a product can be, you better fucking nail your execution.
The people that actually would benefit from this technology deserve better.
