Autopilot, GPS430, fuel computers etc is not necessary if you are in touch with what your flying.
I don't mean to be impolite, but it sounds to me like young and proud talk.
Even as part of a CPL/ATPL training they are absolutely necessary in the way that you have to know how to use them and when not to use them since every modern aircraft is equipped with them.
Being familiar with your duty implies understanding and knowing the tools at your disposal, and how some of them could mislead you. Plus in emergency they can come in pretty handy (to be able to know the remaining fuel, the autonomy/distance available, nearest suitable airfields and associated freq. and facilities in one click while you can still fly the plane is no small deed).
Though VFR initial training should remain dead reckoning and look outside (can't agree more) modern commercial aviation is a bit more than that, thanks.
Its a motor action - trees getting bigger so pull stick back!
In this case maybe, but I hope for you you don't fly by motor actions...
