If you are going to make statements and provide links then of course you are going to be held to account if they are wrong or based on assumptions that are incorrect. The only future designs that the major manufacturers are currently working on, that they intend to actually sell to airlines, are reworkings of current designs. A380 A350 ,B777 ,B787, A320 ,B737. All designed and certified with two pilots on board and all intended to be around for the next 50 years at least. A reasonable estimate of the working life of my children.
