I was impressed what Steve Johnson said at the Unix 50
celebration, about that AI program which learned a game from
scratch in a few hours, just by interpreting "the pixels" that the
game produces on the screen ... and became better than every human

Maybe visualized impressions will be interpretable at one time.
If i approach an "Oracle of Delphi" mind state with a "clear"
picture of where i want to go to, where i want the entire thing to
end up with, then i write good code. I had this not seldom when
i was younger .. but maybe i just should take long walks more
often again. Freud did one every day.
Of course you are right, you will likely need to focus your mind,
and that requires an intellectual context, knowledge, to base
upon. That requires many small learning steps, that surely will
not change. In fact in the western world times to learn are much
too short in my opinion, the normal way of other cultures is
a flatter learning curve, which gives humans more time for personal
development. The latter in theory, of course. But an imbalance
of technical knowledge and development of a personal state of mind
results in things like "have it magically appear".
This is not what i mean. I would rather like it like those magnet
paint tablets from the 70s, where you paint something and then,
swoosh, everything is clean and you start from scratch. This is
nothing new, we had this in many Science-Fictions, but mostly with
speech interaction, like "no, stop, not that; back two steps" or
something like this. But by thought. I think it must be fun,
today you see all the people looking into their smartphone, then
you are surrounded by truly autistic persons!

substantial amount of thoughts which are put into first person

One must face that many, many brains not only have a deficit in
possible targets for thinking, but also lack the motivation or
overall interest in developing them.
Our educational system does not seem to be interested in
addressing this issue either.

Linux kernel, horrific. I currently write an audio-CD access tool
for Linux (since cdparanoia and its successor cd-paranoia seem to
be broken, and whereas cd-info seems to be ok its tarball is about
30 MB, and i thought i can fit this in about 10 KB, and i do rely
on the kernel to drive /dev/cdrom for me, anyway, we are not in
the 90s or so), and i had to look into the kernel source to figure
out the actual limit, and why there is one, of the number of audio
frames i can read at once. The good news: it is open source!
(One may not read more than a second at once.)

That is fantastic. I absolutely agree, and how often have
i trapped myself because of missing comments, or non-talking
variable names. It is all so logical and clear when you actually
write the thing down, you cannot imagine that you will be lost in
a forest in just a few months from now. That is human brain pure.

With the exception of some overall comment blocks at the beginning
of files, and from a very superficial point of view, i do agree.
It seems to be expected that you carefully grasp the entire code
context, so that the necessity for the rest has vanished by
itself. I am not a kernel person, however.
But mind you, that is just how it is with Linux. You do not even
get an acknowledgement if you report dramatical kernel bugs.
I think i reported four or five real in the ~9-10 months i now use
Linux on bare metal, iof which two/three would have been deadly in
earlier times (Linux kernel survives crashes of a thread). I did
not get feedback for anything. But two were fixed as time went
by, that is the good news.

Interesting. I have bookmarked a presentation of her to look at
when i have free time/download again. I would think substantial
amount of money has been pumped in this area, but i never cared.
I work best when i take a long walk in nature, and hope that i get
kissed by the muse. ^_^ Then come back with a "mind map" of what
there shall be. And implement it pretty naked vim(1). ^_^
It seems i do not do all that good enough today.
What i think is that having those new possibilities could possibly
attract more people. There are so many techniques to train your
brain, to strengthen memory, for example, to memorize tremendous
amount of data somehow, for example by "placing the data on
a virtual walk through the flat", and similar techniques. If
people had the option to use their very own imagination, and
having computers map that, i think that would be interesting.
So i think, whereas the actual diversity in between people is
pretty minor, all that software now offers are colour themes and
possibly 3-d effects and whatever, but that is all optics and has
nothing much to do with touching peoples individual "brain needs",
aka it does not reach into their inner world in order to, i just
read that nice american term last week, "milk the shit out of it".
