I agree with most of what you say; however.. if you consider some novel ability like speaking a foreign language, I would think that your aptitude in such a skill is a product of many factors, albeit memory and recall being paramount. If what Elon says about this device is true, and we can use it to mentally interface with the web, then I don't see what would stop us from speaking new languages "on-demand".

Not sure what the delta is between practical applications like disease treatment and this somewhat sci-fi scenario, but I hope it is large.
