You already have to compensate for far more than 5 milliseconds.

Read the post above about how the brain estimates motion. Extra delay when viewing throw this off.

Even prefocused with the fastest DSLR's, the shutterlag is already 40-50 milliseconds. Meaning that by the time you decide to hit the shutterbutton, the bird still moves for 40-50 milliseconds.

Exactly - but as humans have been tracking objects and predicting their future position based on direct observation for a long time; this is a problem we are well equipped to solve.

Entering AF into that equation, adds another 90-250 milliseconds. And let's not overlook the largest delay, the human reaction time, usually being the longest.

I take it you don't do this type of shooting very often.  It's not point and shoot, but you acquire and then follow the target. Like your brain, a good AF system will begin to do predictive tracking.  You can then start shooting single or burst as you continue to track the target In the viewfinder.  Yes, there is blackout but again that's a type of condition we are very well adapted to.  (You dont lose the ability to track a moving object if it's behind a picket fence do you?)
