The dual wake-up call from AMD and from Apple (ARM), combined with the money Intel has in its pocket will have a serious influence on the cpu market. Unsure if they'll come out ahead, but it will get interesting and probably cheaper, not only for consumers.
To their credit, Apple takes the time and invests the money to build the stronger house.
Still ibm then have no consumer whilst apple now has no business and cloud business domination ... still lots of space to play.
But if windows moved to arm with the same result I cannot say intel can survive though.
In 1968 there weren't that many computing devices around. When video games and home computing came around, there were massive opportunities and the entrenched players missed some of them.
Same with mobile phones, same with the internet, same with smartphones.
