90s actors comparing to todays!!!

I've been watching a lot of early 90s movies.. What I have noticed that by mid 90s.. Bollywood is dominated by the same actors that are still dominating the industry.

I mean the 3 khans were big... but also there was akshay, ajay, saif and sunil Shetty...

yea saif and sunil may not be as big of star as they were.. but the rest of them still have name value...

my question is.. would the actors from today survive 20 plus years from now?

I probably can only see ranbir and ranveer lasting that long.. the rest will fade away...
