No, and its annoying that you're asserting things you clearly don't understand. As I mention elsewhere, the only technology we currently have for precision instrument landings in zero weather visibility (the only 100% autoland) is the ILS CAT IIIc approach. The overwhelming majority of airports in the country do not have that infrastructure, nor do most airplanes. I'm a pilot, you clearly aren't. There are numerous other factors here, but just the fact you can't land wherever you want, at most airports with most aircraft, is enough to prove your assertion false.
