Are the current 20~25 players a lost generation?

Most tennis greats made their breakthrough in their early 20s or late teens.
Fed won his first GS at the age of 21. Of his generation, Hewitt won first at 20. Roddick at 21.
Then, Rafa won first at 19, and Novak at 20. Of their generation, Delpo won first at 20, Cilic and Murray at 25.
The next generation of players currently in their early 20s have not won anything significant, not even a masters. Nishikori at 25 has reached a GS final and a masters final. Raonic and Dimitrov only GS semis. Tomic has reached only police stations.
I don't see any of them winning multiple GS, if ever at all, in their career. Is this a lost generation or what?

Big if true

Obviously that generation is dead. Now it’s basically tiny…. Ruin… and carrot. Otherwise there’s no potential in the top 100+
Sad state of the sport.

Police stations are prestigious events.
