Why manned space flight? What is the role of people?

I think it is a great disrespect for human life to engage in manned space flight at present.

In fact, people can operate remotely without going up. Don't all unmanned spacecraft need people to think and manipulate? The same thing is that people on the ground are tracking, controlling and thinking.

It is impossible for space immigrants to move into such a small spaceship. It should be a giant space station or an extraterrestrial planet with production capacity.

In fact, according to the current scientific development process of mankind, it is better not to develop manned space flight, and space experiments can also be done by robots and manipulators instead of people. In fact, it is not too late and logical to study manned space flight when there is a realistic demand for space immigrants, and the research cost will be low then.

Manned space flight is to sacrifice the economic interests of most people, even the lives of astronauts, in exchange for a few people to engage in an arms race.
