Are you implying that they built in artificial stunt thermal issues in those 4 year old laptops, so that they can use that as marketing to sell more m1 devices 4 years in the future?
Yes. It’s one of the main selling point of m1 - being faster than intel and colder than intel. M1 is just a continuation of their A line which exists for a decade, so it’s not like it was a stab in the dark.
