For POW coins, some people think that only anti-ASIC can be mined fairly, in order to prevent the concentration of hash rate and ensure decentralization. But other people hold the opposite view. They believe that it is ASIC that strengthens the security of coins. For CPU mining algorithms, large data centers or cloud computing vendors can easily launch 51% attacks.
Do you think anti-ASIC is necessary?
Think there is no real answer. Some ASICS tend to be expensive so being truly available to any and everyone isn't really achievable which is why some people are against ASICS. I don't think asic/gpu/could mining one vs the other is more 51% attack preventable. It relies on how much hashpower is being thrown at a particular chain.
