If Amazon's stake in Anthropic goes up 10x, but American national security is fatally compromised in the process, I kinda doubt that's net profitable for Amazon. They're not going to be able to deliver in 2 days or hit AWS sales targets if everyone's drowning in cyberattacks.
Isn't that what the entire billionaire class has been doing for decades though? Making profit go up and up while destroying national security? They don't seem to feel it's a net negative.
No? I'm really not sure what you could be referring to. Tech billionaires are if anything too willing to follow the government's lead on national security; they don't seem to have particularly minded the whole PRISM saga, even knowing that it would fatally compromise their relationships with privacy organizations.
National security doesn't mean the MIC, it means the factors that enable the country to continue to exist.
