Yes, it's all very poetic. Can you define it though?
What else did "we" do? Were "we" the nazis? Or were we the allies? Were we the indians or the europeans? Did we write "All along the Watchtower"? Did we invent the first digital computer?
There's the inclusive we, and the exclusive we. For example, "We defeated the Nazis in WWII" clearly means that the person talking considers himself part of the Allies, and excludes the Nazis from the group. "We fought in WWII", however, is inclusive, and includes all sides in the conflict.
So yes, "we wrote All along the Watchtower", as in, we as a human species brought ourselves to the point of being able to write that (or, one of the bazillion different ways of interpreting that sentence). And yes, "we invented the first digital computer," could mean that you refer to the assumed implication that (some of) the people reading this board are software engineers, and "we" refers to that professional group.
But it gets a lot more fun than what you imply: there's the editorial we ("We have always fought for free speech"), the author's we ("by combining the ingredients, we obtain a compound called..."), the dictatorial we (used by managers/team leads, quite often, "We have to finish feature X by Thursday").
Edit: Removed <em> tags.
We should cut the BS, and stop bike-shedding on the use of "we", whose use has been accepted for millennia when one speaks of the collective whole that is humanity and its achievements.
Either way, that's up to you to solve on your own.
In this case we means humans who are able to benefit from, or perhaps simply learn of, the discoveries of other humans.
I'm pretty sure it isn't.
