The 7 stages of AI

The rest is up to AI where it trains itself through self-playing of chess games.
Initially it plays like a novice and builds up skill levels based on the number of self-played games.
This is the “knowing” or skill level part.

As discussed earlier in this thread “awareness” is a topic which tends to confuse the issue in AI as we humans have problems in defining what exactly “awareness” is, which hasn’t been helped with recent claims in the field that AI has already become sentient.
I don’t believe AI has become sentient but there is the property of creativity which involves “knowing” and transcends the application of knowledge or “doing”.

Up to around 2010 computer chess engines were based on the gradual improvement of conventional computer chess programming dating back to the 1960s running on increasingly powerful hardware.
The early versions of these programs were brute force where the program would attempt to find all possible moves down to a particular search depth, to be gradually replaced with a selective depth search based on human knowledge programmed into the engine.

At best these engines were better versions of human players.
With the advent of reinforced learning, AI chess players are not only better versions of human players but play with a distinctive non-human style.
Humans did not create this non-human style as by definition reinforced learning does not involve humans.
The creativity comes from AI itself where it is “knowing” without necessarily being sentient.

Do you remember M chess - it was a tough cookie to beat on highest grades.
Fritz at the time wasnt bad but far easier to beat.

It was the first time cheap commercial programmes got over 200 ECf grade -say 2300 elo.

I remember the days when a guy called Brian levy began analysing the scope of the problem Pre PC
He Wrote some articles in Baruch woods “ chess magazine” At a time there were not even cheap calculators!
How much memory , computer power it would take , in the days of cards and paper tape.

Its only in the late 80s pcs got beyond 1 m ram and 10-100m disk.
Its hard to remember now but in 1990 a single image wouldn’t fit in PC ram!
Array processors were only Tens of MOps, Although could be networked (, which was the bane of physical modelling - eg weather and signal processing too)
Since then both computer and memory power growth has been exponential growth
, and that rather than cleverness overwhelmed it.

Mchess itself fitted on multiple 1 m floppy disks.( who else remembers them?)
Those programmes were in essence a deep opening database , candidate moves, analysis 5-10 moves deep then mechanised positional analysis which is how players of the time did it too. (The cleverest of them like Fischer were better able to assess position , and could certainly analyse deeper Who remembers when he thrashed other grandmasters 6-0 in world champs games! my idol at the time!)

But Brute force has allowed the problem to be overwhelmed rather than solved,
With the ability to analyse 20-30 moves deep and big hash matrixes of 6 endgame pieces etc,

The point I am making…
the reliance of brute force has REDUCED the need for accurate positional assessment, because the search depth allows the positional advantage ( at say 5 moves ) to translate into material advantage at 10-15 moves or big positional advantage which is far easier to measure, for a man as well as machine. But a machine can think quicker and do more.

Humans have a harder job Because they can never analyse so many or so deep variations , they still have to be better at positional assessment.

in short human reasoning is more versatile than machine , but overwhelmed by mechanised power.

I’ve not followed it last couple of years but

The 2800 elo grade seems to represent pretty much human limits,

By the late 1980s chess engines running on the very slow PCs of the time could beat 99% of all chess players.
Here is an interesting video on the improvement of chess engine performance since 1985 and how they are now way beyond the super grandmaster level of 2800 elo.
