so dr lanka would go out and find someone that has drove a car for 70 years without a car crash. and then believe no car crashes ever happen to any cars/drivers(facepalm)
here is a fun fact for you
spiders and viruses are not clever, they do not have brains to make a conscious decision to not become harmful. what happens is natural evolution where each ancestry mutates and where a spider with all the markings of a black widow but has less venom is still not attacked by others. but ends up living longer because it just doesnt bite large species and thus is not swatted/stamped on as much and so the non venomous version ends up living longer
its not a conscious intelliagent thought. its not something that happens overnight. it happens over many many generations
same goes for some viruses. like the algae one that has been around since ancient times when you analyse the sequence to see what family it belongs to
it didnt just pop up in 6 months suddenly being harmonious. over many thousands of years a variant that is less problematic to the host was able to replicate at such a slow rate the algae outgrows the damage caused. thus allowing the virus to continue replicating longer without killing the host
thus mutation is not a thing that happens after 1 generation(couple days-weeks) this is something that happens over a decade/century/millenia
so to rpre-empt your future flip flops
if you think that sars can mutate within a few months to become symbiotic. then you really are not understanding the facts of life.
and if you think that viruses do no harm then you are very ignorant.
you seem to be stuck in a binary thought of symbiotic or deadly and you think there is no inbetween
you think sars-cov-2 infects people and everyone has no symptoms but then must suddenly die. because you keep ignoring, avoid mentioning the amount of people going to hospital with severe symptoms
The fact that there aren't any viruses shows that it is the medical liars who are clever.
