That's a little longer than I would say, but I agree it's going to be delayed painfully long.

What do you think so? Almost all potential problems are already solved. And there is enough crazy people in the world, to try this much earlier...

Just my prediction that many issues will come up. The government isn’t going to let a hunch of humans outside there control in space

First of all - which government? :)

many issues will come up.

yeah... probably, but many issues also come up with other Mars missions: https://en.wikipedia.org/wiki/List_of_missions_to_Mars

but still, there are more and more new missions, and more and more problems are already solved.

First people on Mars will be remembered forever. A lot of people want to be remembered ;)
