i don't think it's obvious at all that visual programming languages don't represent how a computer works, but actually, i don't even see how that matters at all

i don't think it's obvious at all that visual programming languages don't represent how a computer works, but actually, i don't even see how that matters at all. for labview, i feel large programs benefit tremendously from its dataflow nature. every labview project i have worked on has exceeded 1,000 VIs, and it's often very easy to componentize things such that local changes stay local. labview works fine with source-code control. the diff and merge story could definitely be better, but they are at least usable, particularly the diff.
