A long time, considering Alcaraz would have to get to 23 to catch up and Nadal took about 20 years to get to 22. Unless you think there's someone else on the horizon who's likely to win a bunch of them in the same timeframe.
In fairness, Alcaraz doesn't have Djokovic and Federer to deal with, but he has already had some injury issues, so I suspect he won't have the longevity of the big 3.
