Ask HN: Is Silicon Valley Finance at War with New York Finance?

Is Silicon Valley pumping up valuations via acquisitions to drain liquidity from the system so only those with massive cash holdings (See: Apple) after a crash can purchase every single last wave tech patent in one fell swoop?

Theory: New York won't lend money out to the losers in the scenario, but Silicon Valley will (Huge cash holdings), allowing them to clean up last wave's patents while establishing capital for the next wave, and thus, become a investment banking power all their own.
