When do you think the mankind will finally land on Mars?

[Qwark]

When we figure out how to pay for it and when there are actual added benefits of sending humans to Mars outside of it having a big technological dick as a country. We can do many things already with the drones we send to Mars, so what do we really need humans for on Mars to figure out.
If it's just to do it to show the world we van that's a dumb reason when our own planet is getting more inhabitable by the minute and funds should be spend to make earth more habitable instead of less. Although we also spend a shot load of funds on war and killing eachother so perhaps a country ends up doing it just for the heck of it and showing their tech, it might actually be plausible
