The three points to note are:
● 4m 21s, in the third video... Peter Diamandis explains how in the 1840s aluminum was more expensive than gold or platinum. Regarding the book Abundance.
● 13m 12s, in the second video... Eric Schmidt said: "...so we are beginning to see science fiction become a reality."
● 12m 6s, in the first video... Charles Bolden said NASA is going to turn science fiction into science fact.
Over the coming months and years I will add more important videos to my list of important references. The fist update occurred on 21st April 2012 when the fourth video was added, regarding an astronaut speaking in a U2 video. The astronaut said @ 1min 45s:
"We're just trying to do a simple thing, which is to remind people back on Earth that the impossible is possible."
