I do agree with some aspects of S curve but I disagree in that it supposes that usd/btc will stabilize over time. My thought is they won't coexist and the system will become increasingly unstable then go to infinity once the UoA (peg) breaks and $ as a unit of measure will fail like an elastic ruler. Bitcoin is the only unchangeable ruler to measure the world. Bitcoin going to infinity in dollar terms is the same as saying at no point in the future will it make sense to go back to dollars.
