I have been working in BCI for 6 years and to me this is a total moonshot (the writing part). There is currently no affordable technology that can scan the brain at the necessary temporal and spatial resolution to even approach the precision of implants. The main problem is that bones and cerebrospinal fluid dilute the currents a lot. I suppose they want to make something like wearable IRM but that is impossible with our current tech. State of the art typing BCIs have speeds in letters per minute. What we need is a breakthrough in sensor technology, if Facebook can manage that then the field will be able to make a huge leap.

If you read through the article they don't seem to be talking about BCIs at all, just a camera that reads subvocalisations. I'm surprised they can be detected visually, but once you do that it's functionally audio processing.
Not to underplay the significance if it works, it'd be an enormous achievement if they could get it working outside of lab conditions, but a BCI it is not.

In article they mention to use brain imaging to detect the speech patterns in the brain. I have limited knowledge of subvocalisation but would not that be detected on the throat? There were experiments with implants using phoneme detection and they worked but that gives you only vowels. I will post the article if I can find it.
