Apologies if this is a topic which has already been extensively discussed, but does it not disturb anyone that in the last week ~55% of network hashrate has been shared between 2 pools? Maybe my judgement is incorrect but it seems like a disaster just waiting to happen. Is moving towards more asic resistant algorithms something which has been considering or is feesable?

It seems in the last couple of years mining has had a pretty dramatic shift into the hands of larger cooperations and governments.

Are my worries justified?
