Say AMD do fall, Intel risk another company coming along that in time could do better than Intel.
Not quite where I was going. The U.S. Antitrust laws prevent a 'cartel' type organization from gaining complete control of a single market. You cannot be the ONLY provider of a product type and have 100% of the market. You cannot hold a monopoly over the entire business and product type.
Somewhat anticipating this, Intel provided their chip architecture to AMD, then a logic chip manufacturer, to avoid this potential litigation and mandated breakup of the company.
What's so very interesting about all of this is that it seems to have been 'removed from history.' If you search the internet re: this topic, you will find nothing but a WikiPedia article describing the start of AMD as very different. I only know this because an instructor in an introductory class was an employee at Intel at one point and pointed out the documentation in our texts (which I'm going home to review now that it appears public knowledge of this is being concealed). Very interesting.
