Anyone who has taken apart a carb knows the sheer complexity they
possess. It really amazes me that carbs work at all, with all of the
complicated passages, mechanical floats, etc. 

I think it is much easier to change a value of a lookup table in software
than it is to drill out, for instance, an idle feed restriction in
a carb, in that I can easily change the software back, but it is
much harder to undrill the passage.

I think that everyone will agree that any fuel delivery system
is complicated in its own way. Even the god-like carburetor found
on a small weed whacker (which still boggles my mind that it works
upside down or rightside up).
