At first, Andreesen is strategically vague such that 'we' may refer all his readers, or even all who'd be considered members of "our civilization".

But upon starting to speak of the label teased in the title, 'Techno-Optimists', he shifts to using 'we' to describe that group, via progressive definition with each successive "we".

The shift from "potentially everybody" to "those defined by this creed" invites the reader to consider: "am I part of this 'we'?"

What other possibilities for what 'we' means do you see in the text?
