While it is always more complex, and the tide has been shifting for awhile, I wouldn't be surprised if people look back on this match as the true end of the Big Three and the passing of the baton.
I mean, there were bubblings starting in 2017 when Next Gen started winning big titles, then the great years of Zverev and Medvedev in 2021, then Alcaraz in 2022, and Sinner earlier this year. But Djokodal and then just Djokovic re-asserted their dominance, and of course Novak capped it of with one of best years in 2023.
But the steamrolling going on right now, and the fact that it will Alcaraz's second straight defeat of Novak at WImbledon, seems to be the moment that signifies the Shift of Ages.
