That is some grade A armchair micro architecture design you got going there.

Apple completely switched their lineup to the obvious next big thing in processing in less than two years, improving efficiency and performance by leaps and bounds. It has had astounding improvements in terms of generating heat and preserving battery life in traditional computing and they did it without outright breaking backward compatibility.

But oh, it turns out three years later someone found an exploit. Guess the whole thing is shit then.

edit: oh yeah and traditional x86 manufacturers have had the same type of exploit while still running hot

edit2: This is not to say Apple is our holy Jesus lord and saviour, they're plenty full of shit, but the switch to ARM isn't one of those things
