I agree with you. The bigger question in my mind is that in 50 years, will we need to even land humans on mars, or will be able to build space-faring robots where we can upload our consciousness and send that instead. Humans, or generally all complex life on this planet is well ... adapted to this planet. Space is very hostile to us. There's a reason why Mars has had six rovers, with opportunity working for 15 years. Distance to Moon (384,400km) is 0.0017 of that to Mars (225,000,000,000km). Humans have spent barely a few days moonwalking.
