I think that ASIC’s are evil, and if Satoshi wouldn't be anonymous hi would make a hard fork that obsceletes bitcoin ASICs, because mining should be available to everyone on their home computer, this is one of the main principles of decentralization.
Exactly. I think that Satoshi never intended for Bitcoin to become centralized with specialized mining equipment such as ASICs. In the whitepaper, it states: "One CPU, one vote", which means that anyone in the world could mine Bitcoin with just their CPU (like it was in the early days). Now, Bitcoin mining is partly controlled by a Chinese hardware mining manufacturer called Bitmain which has the most hashrate on the network. At any moment, it could perform a 51% attack whenever the company pleases to do so (due to political interests, etc), and destroy Bitcoin before we know it. They're releasing new miners for other cryptocurrency algorithms which were known to be ASIC resistant by design.
A new Ethereum miner is on the way, as well as a CryptoNight miner for Monero. Luckily, the Monero team did the right thing to put an end to ASIC mining via a hard fork, as ASICs would centralize the mining process by leaving small miners (which are those who use CPU and GPUs) out of the equation.
Bitcoin could do the same by hard forking into an ASIC resistant algorithm, but given that it's practically impossible to reach consensus (like the scaling event), I doubt that Bitcoin would make the shift anytime soon. As such, Bitcoin mining would become more centralized as Bitmain takes the lead over ASIC miners. It would become unstoppable and manipulated by Chinese government's interests in order to destroy Bitcoin in the long run.
Other than that, Bitcoin would be completely decentralized where no single entity (regardless of mining hashrate, political influence, etc) could gain control over it. That was Satoshi's vision in the first place, where one CPU would be one vote. Hopefully, we could see a more decentralized version of Bitcoin in the long term. AFAIK, Bitcore is a fork of Bitcoin which has implemented an ASIC resistant algorithm called TimeTravel which is hard for ASICs to come by. Finally, Ravencoin has also an ASIC resistant algorithm called X16R which serves such purpose.
Therefore, there are a few cryptocurrencies out there which are far more decentralized than Bitcoin in terms of mining. Only time will tell if Bitcoin would do the right thing to put an end to mining centralization provided by Bitmain. Just my opinion
