Yes. I don't see what concrete benefits we gain becoming such a species, and I doubt it's possible to send live humans to Mars, or suspend life there. This is the new alchemy.

By the actual definition of alchemy, sending living people to Mars can't qualify as such: we know for a scientific fact that it's possible. It's not even particularly challenging to successfully send (and land) living people there, it's extremely dangerous and risky to their well-being to do so. The idea is to not kill a lot of people in the process of attempting it.
