Living in a sim...

[Anomalocaris]

Even if we conclusively prove we are in a sim, it still won't change anything, other than snowflakes and loonies going around killing because there's no extra life in heaven.

I would argue that all we have is our consciousness. And the qualia of that is the same irrespective. So the difference is theoretical at best.

I would say our being in a sim is the only chance we have for any extra life in heaven.    This is because impossibilities can be rendered seemingly real through simulation, so long as one does not look too closely.
