One last time: Tim Cook is the CEO, not the designer, not the engineer. That's why you have staff in those positions. He's responsible for running the company, not whatever it is that you regard as "innovations".
As far as your statistical model, it's BS. First, those with an afib indication or other anomaly will go see a cardiologist in a clinic, by appointment, not the ED. And it won't take "decades" of "double-blind studies" to establish the benefit of early warning, any more than it would take a cardiologist decades to diagnose an irregular heartbeat.
A) He is
ultimately responsible for every BS Apple produces. Every badly designed product. Every product delay, every final released but bugfull version of software. It is him and him only. If other people fail at Apple, he should have fired them before they failed. This is why he is CEO and no one else. This is why he is paid a
lot money. Period.
b) Again, this is false by 100%. If the Apple watch warns an average -but health aware- individual, who is not a cardiologist, an alarm that says: "You have afib, see a doctor" , the user will with 100% certainty immediately seek help. If it is at night or on weekends or holidays, he will show up at the ER. If it is during daytime and he calls an office for an appointment, the secretary will tell him to
immediately go to an ER if a new arrhythmia is just discovered, otherwise, in case of death, the remaining family members of that user can sue the flesh of this doctors bones for giving im an appointment for the next day...
We absolutely have NO idea, how this device works, we have no idea about the sensitivity and specificity of this method, at this time, nobody has. You probably don't know what these words mean, hell even former art student Ive has no clue what these words mean, just blah blah about all his bones... he is implicating, that Apple Watch buyers live longer. At this time, this intentional misinformation just to skyrocket sales is dangerous.
