This is called discursive thought and is very common. The goal of non-dual mediation is to recognize these thoughts and realize they are not you.

If not you, what do you think they are?

You do not need to identify with them. They come and go like the wind. They are no more “you” than your hair on the barber shop floor.

That's odd. Can you silence the voice? Do you exert influence over it?

If I start trying, it completely goes away, replaced by my monologue. I'm sure a lot of people know that feeling where you very intentionally drive your own internal voice. I can do that. I think it's related to my ADHD. Reading is very difficult because as I read, my voice just completely wanders off, CONSTANTLY. "Oh hey, 'gargantuan' that's a great word. Reminds me of a video game monster... Oh did you just read 2…

Yeah, my inner monologue sometimes feels like I'm driving it, and sometimes I am definitely definitely not driving it. I don't know if it's "my voice" or not, it's just... the the thing in my mind that outputs (silent) language.

And yeah, I can have conversations with the voice. Yeah, it can help to focus moving my thinking forwards on some problem-solving thing. But, alas, often when I'm doing that it just starts saying obviously-silly things, as if it's a Markov model. Sentences that might sound structurally reasonable but that are obviously not what I meant to say/think, and obviously not true.

But it almost never interferes with reading. Reading is too compelling. Even if my thoughts go off in some other direction while reading and I do the "just read a page but absorbed nothing" thing, there's no voice involved then, it feels like a different process.

it will still be a blindfold. I dont get the entusiasm about a wearable form factor. i d much rather have 5 screens around me In any case brain implants are the ultimate input device, which will solves a major information bottleneck for work in general.

With VR you can have as many screens as you want. Though you'll need a high resolution headset for it to look good.

And FOV. The virtual screen is a nice gimmick but gets old quick imho.

OTOH brain implants provide for information exchange that is orders of magnitude faster, even if it is just text, as we do here.

How or where did you acquire such specific beliefs about what minds can or cannot do?

My skepticism probably comes in part from an anti-religion, anti-mystic reflex. There’s a lot of woo around this stuff so it often puts me on guard. Obviously nobody is claiming psychic powers here, but I wouldn’t expect brains to operate that differently - so it’s surprising to me.

I see now from your other answer what you meant, I thought you had meant not you in some sense of being externally created or imposed.

I'm curious how his imagined writing compares to the handwriting he had before he was paralyzed. Was it always that messy or are the BCI controls difficult to use? For example, his comma seems exaggerated, as though he had to imagine grand gestures to get the SW to recognize it as a valid character. But on the other hand, his "m" and "n" look fairly normal. It's possible that's just what his handwriting looks like.

Actual handwriting goes with a feedback, at least with kinesthetic, tactile and visual. Here he writes "blindly". I dont' know how much it contributes to the mess, but I'm sure that a noticeable amount of it can be explained by the lack of a feedback.

Interestingly there are people like myself who don't have an inner monologue (some people supposedly even have a constant dialogue with themselves) at all. The only time I experience something like an inner voice is when reading. My normal thoughts are more abstract I guess, I'm just sort of aware of what I want to do, how I feel etc. It's hard to describe.

I've always been a bit perplexed by the claim of not having an inner monologue, but after reading the replies to your comment I wonder if I'm closer to not having an inner monologue than having one. I thought it was about not being able to summon an inner voice at all. Regardless, it's fascinating to read peoples descriptions and see that it lies on a spectrum. I definitely experience it when reading & writing carefu…

In one of Feynman's books, he discusses and experiment that he did with people keeping time in their heads (count 30 seconds) while simultaneously reading a passage of a book. Some people had absolutely no issue with doing this, but many people found it impossible.

When he asked people how they kept track of how much time had passed, he found that people who pictured a number in their heads were able to keep time and read without issue, while those who "spoke" the time to themselves found it impossible to read.

This too will be weaponized. How? Capture a North Korean official, put one of these in his brain and siphon off all the juicy intel. Capture a narco trafficker. ditto. Capture a terrorist. ditto. Have we made the world better? It seems that whenever we develop ANY device for improved information processing, it disrupts the world we live in and displaces the uniquely human style of information processing-rendering hum…

This nightmare scenario fails the "rubber hose" test[1].

...which means that even a modestly sized transformer model could do significantly better.
