Sorry, the reverse is true. It's an interesting insight into human psychology that people seem really personally threatened by robots. Yes, a couple of guys in Meridiani right now would be better than a rover, but it would cost hundreds of times more money to send them there. And the capabilities of robots are going to rise much faster than the cost of a manned mission goes down (IF it ever goes down.)
Given "X" amount of money, we'll do a lot more science with unmanned than manned missions. For the cost of 1 manned mission we could cover mars with hundreds of rovers.
We just CANNOT "Program" ENOUGH into a "Robot" to RECOGNISE what a Trained Human Explorer can see in an "Exploration Mission" to the Moon or Mars.
The Robots are, simply, "Not Up to It!!"
Once More, it will be a Century--or, even, a Millenium--before our Robots are capable of equalling a "Human Explorer" on the Moon or Mars.

That goes double for private enterprise, commerce rather than research.
