Okay, so we've got the mining robots, the auto-fuelling spaceship dock, the autonomous telephone sanitizers... I can't help feeling there's something we're forgetting... Oh! Right - people. Hang on. Why are we sending people again?
Because we're not smart enough to make a robot that could and would do what we'd do and telepresence would be hopeless with the delay. Take the stupidest person you know that can drive a car. Ask him to write the software for a self-driving car, might as well ask him to jump to the Moon. Not even many man-years of the best and brightest has managed to get their car a driver's license that millions of teenagers manage every year. If there's a real base there will be plenty that goes wrong or becomes defective and plenty to fix. If it's just to have humans in a bunker eating canned food until their return flight, then yeah there's not much point.
