Because vaccines were so successful in their harm reduction to even elimination, there h

created a perverse belief that vaccines

were not effective, and then that they were actually harmful. Being ubiquitous and their effects the same, and the absence of their necessary disease.

Tools that solve problems experience a lifecycle that eventually if successful get weilded by people who never had firsthand experience of the problem.

Really a very large fractal problem space.

We envision a similar problem in autopilot system with 'safety' fall backs. For now, autopilots can disengage and let a pilot take control, but soon, we will run out of qualified pilots to disengage to, and no secure safety procedure.
