How can this help the miners?

Will the net decrease? however this is forking time but i heard that there is already some fpga able to mine this algo.

I have been tired of mining ethash from the beginning.  I hope this algo will be better. As usual it will be more profitable the altcoins forked from this algo for little miners. i never unserstood the people that continued to mine ethereum also if it is not profitable . you are losing money. the net is safe . so why continue to mine.
