With the papers that have been done in rodents and primates, the fascinating take-away is that the implanted chips actually do improve memory despite our lack of understanding the neural code. Just like the advances that have been made in brain-computer interfaces that record from the motor cortex, it's quite possible that the brain's plasticity allows it to work with relatively simple circuitry. There's no reason to slow down development of technology like this (as long as it's safe). I believe they've shown some pretty promising clinical results in humans already. Also, they've got some of the best memory researchers in the world on their team (Boyden), so it's not like they're unaware of the challenges they are addressing.
