Along the spectrum of First Word <---->Last Word, my work is more towards First Word because my medium of choice (VR), is not as widely explored and documented like other forms: drawing, computer art, film. Orson Welles put it well when he was talking about his first cameraman, "You never made a picture, and you don't know what can't be done!" I don't know what's impossible. As far as I'm concerned, it's the wild west!
In regards to how culture accepts technology: I think it's based on how well it's introduced, and only well-introduced tech can shape culture. For example, the novel idea of the touch screen has been around for decades before the iPhone popularized it with the first touch screen monitor produced in 1983. That's First Word. When the iPhone comes around and popularizes it and becomes embedded into modern culture, that's Last Word.
