Why send humans to Mars when we can send robots with much less risk and expense? By 2030 we should have artificially intelligent robots that more capable than people. Sending humans into interplanetary space is just a publicity stunt.

You’re right we don’t need to go to Mars. We can just send robots. Going is just a publicity stunt. In fact we never need to leave our couches. Going outside is always a publicity stunt. We can send robots every where then there wouldn’t be any muggings, robberies, trafic accidents, etc. We’d be perfectly safe.

But I’m going to Mars, see ya couch potato!
