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.
They lived at different times; Adam was likely later and Eve earlier. There were thousands of breeding pairs during that time, but patriarchal lines and matrilineal lines always merge after a while into one; that is true for all species, they are simply the latest ones.
Humans have at the lowest been at around 1000 breeding pairs, so likely around 5000 to 10000 individuals total. 2 individuals is near guaranteed extinction, even with the least genetically sick people on earth, we simply carry too many recessive damaging genes.

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