No one is a star expert, that is the point. We understand very little about stellar evolution, as this article highlights. We're estimating a few 100 thousand years left, but that is little better than a guess. For all we know, it could have collapsed already, due to some quirk of stellar evolution that we just don't understand yet.
Best to enjoy what we can see, while we can see it.

"We don't know the exact number" does not mean "you can make up whatever you want". Just accept that you were wrong and move on.

Except, in this case, you could never prove someone was wrong, one way or the other.
Unless we somehow managed to devise a way to teleport an observer to Antares, you'd never know for sure, if it were still there. That is the beauty of light having a finite speed.
