To summarise: A close-up on a technologically enhanced foetus with a Hollywood-style voiceover:
“For centuries man has struggled to understand his true nature.
What is it which makes us who we are?
Soon, one answer will override all overs.”
Followed by a text logo…
“Who we are is but a stepping stone to what we can become.”
What can we take from that? Well, googling for the phrase without quotation marks brings us to a Girl Guide Ceremony, which I suspect we can reject as a direction unless Eidos Montreal really have a sharp-U turn in mind for Deus Ex. More generally, you can - in the context of the actual foetus - take it all as transhuman or posthuman rhetoric. The dual ideas that humanity’s ability to sidestep the basic evolutionary forces that have driven the world, and actively craft our future selves.
