To me, everything is normal till we achieve immortality escape velocity, and it becomes clear people will be able to live forever.
It's fairly easy to objectively measure, as it is when nobody dies from old age.
The question for me would be will we achieve this first by actually curing aging, in all its forms (seems quite hard to me)
Or will it be achieved vea neural engineering of new brains and avatars into which we upload ourselves in reversible ways. I predict this will be far easier, once we discover and start engineering subjective computation with color qualities like redness and greenness and neuro ponytails....
And the latter has the advantage of curing accidents, as you obviously have backups of yourself.
