Yes we all get rusty when we fly a managed cockpit.
But we still have the basics hard wired in even if they are rusty and its still there when it goes wrong even if its not quite as slick as when you were wanging your 707 round. But its still there.
An instructor for example is hardwired to lower the nose if they think they are stalling. They have more than likely stalled an aircraft 100's of times. They know that holding the stick full back is never going to save the day unlike the AF447 pilots. Thats going back to WW1 flying and dealing with the stall.
And to be honest though you haven't really said anything which desputes the point.
In essance if someone else is paying for these courses or has a deal going go for it. But if your self financing don't subidise the big boys training costs.
