Flight instruction still builds hours and life-saving reflexes when students do the most unexpected things. I want my captains to have lots of those hours.
I had lots of light airplane time when I went with my airline. That included a lot of actual instrument flying, including approaches to minimums. And, none of those airplanes had auto-pilots. Almost all was single pilot. And, I was an instrument instructor. In my case it wasn't being instructor that prepared me nearly as much as all the hand-flown en route and approaches to minimums.
