Beginners see an engine evaluation on move, I don't know, 8, and think it means something.
The only real evaluations are win and draw... and so when you explore openings more deeply they'll either tends toward win or 0.00
By exploring deeply I don't just mean letting it reach a high depth, I mean putting the moves on the board... sometimes for dozens of moves.
Nearly ALL openings tends towards 0.00 with proper analysis -- but this means very little to human play.
This game was played recently, between Stockfish15 and LCZero:
As you can see, Stockfish 15 (+NNUE) was unable to crack the King's Indian Defense.
I believe the KID is likely a draw with perfect play from both sides. But in OTB play, black sometimes has to make harder practical decisions.
That doesn't mean it's refuted, though - it just means that it's sometimes sharp and treacherous. The same can be said of the Sicilian.
