amd are richer than Intel now so chances of them dropping off the face of the earth are non existant. Ok Nuclear war taking out the mideast, germany and the US would see AMD cease to exist, other than that, no. Owned by trillionaires now, doesn't really get any more secure frankly. As for prices, its not in Intels interest, even without AMD, to make chips unaffordable. Its better for them to sell 1 £200 chip every 2 years, than make the so expensive people buy 1 £700 every decade. Cheaper they are, more that buy, the more that buy, the faster companies make use of more cpu power as you have to have the majority of your market at level X to make it worth making software Y that can use level X. So the more chips they sell, the more software increases in power to use the chips, the more demand is generated for more powerful cpu's, etc, etc. If they tripled the price of every chip they'd see profits drop massively. some rising prices yes, all their "we'll make this chip $50 just to see AMD sweat" chips won't happen, but other than that, no.
