I predict most airliners will be autonomous by then. Maybe a Safety pilot on board. But they'll do no more than sit and push the odd button. A Shared senior pilot will be land based and accessible on com. When they go single crew, they;ll have to design them to fly with a zero hour pilot on board. Because without the two crew environment, there will be nowhere to learn the trade. Ryanair must be wetting themselves at the prospect of getting rid of Captains and keeping the PTF children.... On minimum wage....
