Just give this hour long show a once over; this is Elon Musk on the the Re/Code Conference 2016.
Elon is as always very vocal of his deeds and why he is doing them. But it is the questions on Colonizing Mars and re-usable rockets which has him on the edge, big commitments and all!
The excitement is big on his face all along (not too sure of the interviewers though, sadly).
If you do manage to reach the end, pay attention to the (pretty mature) audience questions. Especially the "living in a simulation" one.
For the un-initiated, the simulation hypothesis proposes that we, the humanity, are the creation and inhabitants of an artificial simulation in a simulated existence and "of which we, the simulants, are totally unaware."
This is most likely an outcome of the evolution and advancement of a very advanced version of our or a very similar civilization.
The concept is pretty much a mind fu*k in itself and has a quite a bit of the Internet dedicated to it.
Anyways, the Elon discussion is a must watch if you really want to know about the next big things around the corner.
