Nowadays, I recognise that it is heavy engineering, but I am not so impressed by the fact that we are throwing so much resources at something that we already know we can do. In fact, we have had humans surviving in space for decades now. It's costing a lot, it's not bringing much.
But more than that: we have much more important problems to solve, starting with our survival. Sure, sending robots to Mars is interesting, for science. Sending people to Mars is useless. Hoping to become an "interplanetary species" is preposterous. Thinking that Mars is "just a next step, but we'll go further" is absolutely insane.
Life is literally, measurably dying on Earth (the current mass extinction we are living in is happening orders of magnitude faster than the one that killed the dinosaurs). We have a huge energy problem, and more and more global instability.
Sure, watching four humans happily travelling to the Moon in a spaceship that literally does not need them is fun, like watching the Superbowl. And like for the Superbowl, there are big fans for whom it is the most important event of the year. However, most people don't care. We're not in 1969 anymore, now it's just a matter of wasting enough money for some people to have the time of their life.
