If you are not old enough, you didn't see the days when a world champion could beat dozens of best computer chess programs even in a simul.
In 1997, the equilibrum has shifted in favor of the computers, after Deep Blue has been the first computer to beat a human world champ in a match.
The 6 game match is a historical moment of the human vs machine, so there have been many books & publications & media articles about it.
Let me share two of them, although not very recent, but still interesting to read:
1) @ THE CONVERSATION:
Twenty Years on from Deep Blue vs Kasparov: How A Chess Match Started the Big Data Revolution
2) @ TIME MAGAZINE:
Did Deep Blue Beat Kasparov Because of a System Glitch?
3) @MEDIUM.COM: CONVERSATIONS WITH TYLER COWEN (BONUS PACK):
...and the third, as a bonus, speaks about the future of AI from Kasparov's point of view. Don't forget to read what GK suggests about a match opportunity between Magnus Carlsen and the strongest computer program available (Stockfish?).
