Thinking about BCIs a bit tonight.
Nothing profound or technical. Just a thought or two.
Imagine being a writer and having access to a brain-computer interface that has already been adjusted to your thought patterns and recognizes general concepts and symbols just by recording the amount of water in the blood passing through the brain, or something along those lines.
You might be like me and have an extremely active and vivid imagination.
This BCI could theoretically allow you to write a story just by maintaining a train of thoughts. The output might not be what you desire... But that's why you have a BCI, which can allow you to immediately rectify a mistake using the same process.
If it can reconstruct words, it can build images as well (the same ability NLG models have, but operating through different means).
This writer could conceivably construct picture books and, potentially, entire films just with his or her mind.
They could then send it neurally onto the internet, where it could be read by others who neurally scroll through an e-reader.
This is my particular dream above all: hands-free digital feedback. At my fastest, I can type at 86 words per minute; when I'm on a roll but not speeding, I can average roughly 45 to 60 words a minute for a couple hours non-stop.
A sufficiently advanced BCI might allow me to "type" the equivalent of 500 words a minute or more.
To put that into perspective, the lower limit of a "novel" starts at 50,000 words. That means that this hypothetical BCI could allow the writer to finish a novel in roughly an hour and a half.
