When the algorithm changed implemented in ZenCash network, I believe it can have big impacts (positive ones) on the community.
It's always good to become ASIC-resistant, because coins with ASIC-resistant characteristics can have stronger ability to deal with dominant hashrates, which in turn prevent potential attacks.
This is an ill-conceived thought process. A coin that can only be mined by GPU and has a low network hashrate can be attacked by renting GPUs from Nicehash or Miningrigrentals. Why wouldn't someone try a 51% attack with bitcoin? Because it's network hashrate is too high to make it worth the effort... this is due to ASICs dominating the network.
