Since I have no faith in the US dollar, I originally was not interested in this. Why stabilize something to the dollar when the dollar is so inflationary? I buy something today, a month or so later it will cost more, and each few months later, the cost is higher again. I compared things I regularly buy and a year or two earlier they were significantly lower in price. So the DAI is stable because it is matched to the dollar? No. It becomes just as unstable as the dollar. Perhaps the DAI will not be going up and then down and back again, but basically it means it will continue to go downward in value for goods.
That being said, the concept is good for the stability for managing a retail business and the security, infrastructure, and principles behind it seem very sound. Sure beats the banks we have today and avoids the centralization and introduces accountability.
One big question: If the dollar crashes, what will the DAI then be "against". All the various kinds of collateral is excellent, but the whole theme is to be tied to the dollar. If it crashes, why would we even want it? Needs a backup plan for that situation.
