Lets hope that regardless of who holds the majority of the hash power, they recognize that its in their best interest to maintain the integrity of Bitcoin.

Once the halving increases a few times and there isn't so much money to be made from mining, perhaps they will start to shut down some of the big mines which would allow it to be more distributed?

What if we encouraged individuals to run a miner each, even though they wouldn't make any coins, if enough people did it just to help spread out the hash power it would help, correct?
