You guys should actually do an autoland in a real jet. It works great until it doesn't, and when it doesn't, you need a pilot there to intervene immediately. A single pilot could certainly do it (if you forget all about this industry's CRM advances that have PF/PM roles as a cornerstone), but in the event the pilot is incapacitated? Good luck. For the sake of the 200 people behind him, you'd better hope the autoland works.
I simply don't see it. Nobody is saying the technology doesn't exist, or couldn't exist. You'd just have to rewrite decades worth of CRM and safety philosophy to make it happen.
Autoland didn't exist when turbines first came about. Now it does, and I'm willing to bet a pastrami sandwich it's an option on every Boeing made. Technology slowly advances. In time, it could be a 99.9% thing, and the .1% may be viewed as an acceptable risk.
