Will Elon Musk's speech on Tuesday laying out his plans to colonise Mars come to be seen as one of the seminal moments in human history, the catalyst for our species becoming multi-planetary?

Questions around how he'll raise the funds, is it technically feasible and who will be mad enough to volunteer for the first flight aside, I think this is massively exciting. We're about to see billions of dollars of funding directed towards pushing the limits of what's possible with the goal of making Musk's dreams a reality. From materials science to zero-g games, the mission to colonise Mars will drive innovation in a wide range of industries and could be the catalyst for a new generation of entrepreneurs with big ambitions.
