Anyone who thinks that UAVs are just over the horizon for operating for commerce in the US needs to take a look at the military's accident rate for UAVs.
What kind of redundancy are you thinking of? The military has UAVs that are designed with several layers of redundancy, and they STILL lose UAVs for lost signal (or any one of a number of other problems related to not having a human in the aircraft) all the time.
It's not that big of a deal when a UAV is $1-5 mil a pop, but with a $100+ mil aircraft like Fred's thinking of, it is a BIG deal. And that's just with an "unmanned" aircraft, where there actually are pilots making decisions about how to operate the aircraft. Fred wants them to be robots!
This is the part that is the most interesting, in my opinion. I think this shows a fundamental misunderstanding about the role of a pilot currently. Fred is perfectly happy to point out that pilots do about "20 seconds" of work. Yeah, that's true, so long as everything goes exactly as planned. The REAL reason to have a pilot on board is to handle decisionmaking when things don't go exactly as planned.
To be sure, most accidents are caused by pilot error. BUT, if you consider all the mechanical and avionics malfunctions that happen on a daily basis that don't turn into accidents because of human intervention, this number would be significantly lower.
