If by "we" you mean robots we create, then I think we may yet do that. Human space endeavors will likely be the product of private venture IMO and not NASA.

What is the financial incentive of sending humans into space instead of robots? The first way to slash huge chunks of unnecessary cost for company xyz's asteroid-mining project (as an example) is to ditch the human presence.

I personally believe we need both humans and robots for studying and studying in space. In some cases of course, humans are unneeded and any robots can be used as a proxy so to speak for humans, but you have to keep in mind there is no computer (or at least not one we can send into space) that rivals anyone's ingenuity or curiosity, which is exactly what is need for many studies.

Increasingly it is starting to look like NASA's direction will be robotic endeavors while private industry like Virgin and SpaceX focus on human space endeavors and recreation. Which is fine by me, it's my hope that the two can exist symbiotically.

I agree that humans have a degree of flexibility that computers will not have for a very long time. I'd say, however, that this flexibility is not of extra use more often than it is. What was the last time we took scientific data that absolutely required a human to be along for the ride? Tack on to this (1) that spacecraft can be remote controlled safely from Earth, (2) autonomous control systems are getting smarter and more powerful each year, and you have even less practical incentive to put a human on board. Obviously if the distance from earth is significant, the degree of control is lessened because of the transmission time, but that's another discussion.

I am a staunch supporter of a continued human presence in space exploration, but I can't deny that the current state of technology and funding make it utterly impractical. The benefits to having humans along are almost always outweighed by the drawbacks, especially in an era that struggles with heavy lift technology. Perhaps the solution is to simply wait until propulsion, life support, and launch technologies mature.

Very good point. There are many more situations where we can be drawbacks, and at this point human presence is more of a subject of wanting than needing.
