Any level of interest would make sense. They should do literally any single thing that the characters in-universe might/can do. But they have zero interest as far as we've seen. That doesn't make any sense if the characters care about anything.
What is this point about the specific time it will happen? It's a race, they're actively hurting their chances by doing nothing. It's a growing problem that gets worse by the minute because there's other factions who actually do care.
Like I said, that's fine if they acknowledge it, but as far as we can tell they have no thoughts or conversations about it. That makes no sense and makes them non-characters.
Why argue about this when you're clearly just looking at it from just a meta-perspective?
I am not looking at it from a meta-perspective.
Your are the one that is not looking at it from the SH or luffy perspective .
What do you think is more important to robin right now ?
Seeing the person that help her make it through the last 20 plus years when she wanted to died until she meet SH or the last poneglyph.
Do you think luffy is in a rush for last last poneglyph and don't want to explore the island he and ussop has been dreaming of or enjoy robin being happy with rest of the crew or party with people that help save them on egghead .
It's always been a race but that never stop them exploring and doing what they doing .
You want them to care about something much more than they would when there is no hard time limit on world ending which make no sense.
Should the SH hurry back and ask ray for directions or get the 2 AW they know about since the world ending on some unknow time limit ?
No they won't because once again there is no rush in there minds and if anything doing what they doing is what made them get this far in the first place.
You want them place something they have no info about above everything else in there lives which would be very unlike them .
