Well, most people don't mine idealistically, so my idealistic visions will probably never see any kind of adoption.
There will always be bigger sharks and smaller whales... I do not expect a househod to drop a large sum of funds to invest in miners, so they can get some mining revenues and (hopefully) ROI in a descent time and make profits. There will always be people with some cash to spare, cheap energy and the will tto scale up in order to get a bigger piece of the pie.
Mining is a greed driven model, so the greediest people will do whatever they can to get some of it. The arguments for anti-ASIC/farm are specious when it comes to "entry" or the like because they always ignore that scale will happen and for the right $ any firm/group/company can control 175Gh/s in seconds. I appreciate the ASIC resistant coins. It lets some of us smaller scale hobby miners get a slice of the pie a little longer before profitability disappears. Lottery mining is really it for Bitcoin at this point. Without an ASIC farm anyway.
I run a small ASIC solo miner for Bitcoin, just because. It's my weekly lottery ticket.
Cheaper than a lottery ticket and better odds.
