Dak is the equivalent of owning a car that may appear to be free of dents and rust but has numerous mechanical issues and you desire a newer vehicle but simply can't afford one......and every morning you have to live with that every time the car goes out on to the road......all the while wondering if this is the day it breaks down completely.
If you compare Dak's 7 years to any other thing there's not a single person that would trust it.
If your car failed every year while going on vacation would you drive it?
If that plane failed every year on it's oceanic flight would you buckle up and go?
If that roller coaster failed every year right at the loop would you ride it?
No, you wouldn't, so how does one develop such unconditional trust in something that has failed over and over again? It truly should be studied.
