Thank goodness the apparent "avoid risk at all cost" mindset wasn't present earlier in human history or we'd still be living short, brutish lives in caves. Anything else would be too risky.

A long time ago, someone first floated out to sea in a hollowed out log. Over time, better ships were created. A lot of them sank and a lot of people died, but people kept going to sea to this day.

Over time, we developed more means for transportation. Every one of them had fatal accidents. Trains derail, planes crash, and cars kill people by the scores of thousands every year. Through it all, people keep riding trains, cars, and planes.

Will we continue with manned spaceflight? I'd like to say certainly yes, but that depends on our will as a people. We have to be willing to spend the money (a lot of it) to send people into space. And we have to understand that some of them are going to be killed.

Do we have the will to continue? I think so, but then, we didn't have the will to continue exploration of the moon. There's little tangible public support for sending people to Mars or elsewhere. Honestly, I don't know what we'll be doing in space 20-30 years from now. I know I'll be disappointed if we're still going around in circles in LEO. It'd be even worse if we're not up there at all.
