we should rapidly change the PoW algorithm to make it impossible to build custom ASIC hardware; making Satoshi’s vision of One-CPU-One-Vote true again. Therefore, we need a dynamic PoW algorithm. Dynamic hashing could be one way. Another way could be finding a certain sequence of prime numbers, like in Primecoin — the “Cunningham-chain”. Also the prime-number-chain algorithm needs to be dynamic, meaning that the requirements for the prime-number-chains need to change over time.
i highly doubt that we will ever change the mining-algo at this point. this is a 7 billion industry.
