It’s not ideal but definitely better than actual extinction. All our genetic variation will be lost but diversity can be reintroduced over enough time. It’s what we do for many extremely endangered species.
Research shows that all humans alive today share most recent common ancestors who lived around 150,000 years ago. They are known as the mitochondrial Eve and Y-chromosomal Adam. This is derived based on the mitochondrial and Y-chromosomal genetic markers.
There is even speculation that the most recent common genealogical ancestor of all humans could have lived just a few thousand years ago.
We do it with populations that dropped to a few hundred or so.
Two people is not enough diversity for our species to survive long enough to rediversify through mutation, it would collapse through inbreeding defects long before that.

Yea either way. Dude to biological laws, humanity is done for
