Speaking of the plot, I chanced upon the quote again from that pic of the cover of the script, “As new species are formed through natural evolution, others will become rarer and rarer, and finally extinct. The forms which stand in closest competition with those undergoing modification and improvement will naturally suffer most.” I wonder if it's of any importance to the plot at all, because it seems to strongly suggest that it's the humans' future that looks pear-shaped, rather than the mutants'. Could it be somehow about those "very new things" Singer talked about in an interview from a while ago?
I thought that too, even though it isn't what's shown in DoFP in the comic. Curious indeed. Could it be that the time traveller is a surviving human (like Bastion?) who wants to instigate Sentinels to wipe out mutants in the past and save the human race.
