The title of the article is a bit misleading. What will happen sooner than later I was told is allowing one pilot to do the cruise,while the other is resting on long haul flights, thus eliminating the need to carry reserve crews .
Once technology is mature to do this, you can guess where that will lead.
On the other hand having heard Capt Richard de Crespigny account of the QF A380 emergency dealing in SIN 3 years ago, I am glad they were so many in the cockpit then.
