If you consider it progress to switch to a more costly fuel that delivers less performance, then you have answered your own question.
My definition of progress includes concepts such as lower cost, higher performance, and with respect to the environment, benefits which are proven and highly predictable.
Ethanol will not be fueling our vehicles 30 years from now. It is not the fuel of the future. It will be fueling people for many years though, and I'm saddened that I cannot purchase it so cheap for bodily consumption.
