I don't even know if it does make sense to reply anymore.
"We agree on that, but that does not prove they their decisions are totally different and uncorrelated." ++ Well in TCEC they start from the same imposed position and they play it differently
Always. Every engine plays a different move... If there are 34 legal moves in that position, the probability for an engine to play any move m is 1/34...
and sometimes it is win/draw,
How many some times? It's up to us to discover.
thus different moves in the same position and uncorrelated
Of course. If two engines play two different moves in one position, all the moves are in general uncorrelated...
Inaccurate, imprecise, hasty generalization.
"But you exclude that their ignorance can lead to a chain of errors by the two, because they both ignore one made a mistake, but to you at least one of them knows how to play perfectly, even with a flawed evaluation"
++ If that were the case, then the evaluation functions would wildly fluctuate and they do not.
For reasons known to @tygxc only.
engines do not just randomly pick moves...

++ And for 1 GM, 65+ World Champion, famous analyst, MSc. with a profound opinion there are 7 weak players that call him a crackpot speaking garbage.
I'm not calling Sveshnikov a crackpot. He's just a GM who made an exaggeration in an interview. Happens all the time.
