Intel has to leave the X86 processor tech because of its limitations. The performance is lacking and the heat production has been bad for years. ARM does not have these limits and has way more potential, but was filled with doubts back in the day. It would have been a huge gamble that Intel did not want to take. But ARM worked out the kinks and now Intel lost silicon leadership, looking pretty bad still announcing 14nm processors for 2021. Their roadmap says they want to be on 1.4nm by 2029. They have to make huge leaps in development to make that happen. They will need an engineer as chief for sure. It would be a tremendous accomplishment if they can still turn this around, especially with Apple coming out with the pro version of the X1 soon which will be blazing fast, low heat, low power consumption, unbeatable for years.
