AMD could not afford their own foundries anymore. The same is likely to happen to intel. The CPU business may be sold off to some other company, so x86 and intel will "survive" for sure but they will rely on other fabs to produce and they will milk the legacy cow instead of holding the overall performance crown.
Did you completely ignore the last paragraph?
As I said, AMD survived by going into a lean pivot out of desperation. Intel has that opportunity as well, but the deck is stacked against them due to their size and over-reliance on specific IPs.
