1 Whenever I see someone say that a robot can do anything humans can do, and better, I don't know whether to laugh or cry.  The last probe we sent to Mars sat on its lander for days, then sat where it first rolled onto the ground for weeks.  It was over a month before it took it's first soil sample, and they were afraid that it never would do so due to a tiny flaw in a single sensor.  Two astronauts with cameras, shovels, and a soil test kit on their lander would have gathered more data within the first day of landing than that probe did in it's whole mission.  I won't even go into the other benefits such as inspiring a large chunk of the populace, employing a lot of engineers, and making progress towards getting all of our eggs out of a single basket.

2 Good lord, did I brought it upon Steven? At least I haven't mentioned Brussaurd Fusion.
