Nepotism? Like execs from different divisions fighting each other?
To me it seems they just want to keep their lock-in monopoly because they own x86. Very rational albeit stupid, but of course the people who took those decisions are long gone from the company, many are probably retired with their short-term focused bonuses.
The opinion that x86 would always be king is nepotism/ego. It was obvious nearly 2 decades ago where compute was headed with cloud and mobile becoming the dominant areas. Neither of which x86 was well positioned for.
There was a story here a few days ago about the exact opposite: that Intel lost out to AMD on x86-64 because they were betting on Itanic to take over the 64-bit market.
