lets say u're famous, or politician. it is appropriate for u to get an armored car for safety purposes coz there is high chance som1 will wanna kill/harm u.
but if u're a normal person, not famous, no ntgh, getting an armored car, u're just being paranoid. y dun just get normal car?
i hope u understand the metaphor.

yes, unstable OC will harm other h/w as well.....
but dis doesn't mean 10 minutes if prime is not stable. it is very much solid.

metaphor:
it's like comparing 2 cars, car A wit 90% safety rating, car B wit 50% safety rating.
yes, car A is safer den car B, but the point is, lets say minimum passing score is 40%, even though car B is less safe compared to car A, it is good enough.
