There will likely need to be translation layer. Motor signals aren't necessarily tractable either, people can learn to walk again after even if the parts of the brain that govern walking are damaged.

The promise seems more that ideas can be transmitted with higher bandwidth. My signals -> word1, send word1 to you, word1-> your signals for word1 would be likely. Both of us would have to the system for word1, but if we could exchange it much faster than speaking, maybe even reading.

My issue with the system is that the line between reading and writing signals is very thin, and this these are hackable devices. Once the device learns a person's brain signals to make the legs run, it's easy to replay them on a bridge when facing sideways. There's no technology right now that's foolproof, and I'm not sure how any company can boast that it's secure enough — even if encryption is strong laws can still be enacted to force companies to hand over keys or install backdoors.
