That's what engineers do, they are not concerned with conclusions, they are concerned with the root cause. COVID did not wipe out the unvaccinated population, so far. Yet the pandemic is never-ending, because individuals and organizations are refusing to conclude it.

The virus is nothing compared to the fallout. What's worse, the root cause is now stronger than before, ready to carry COVID far into this decade and beyond.

This is what engineers do, they try to find the root cause of the problem.
