The colonies on the Moon and Mars should be going concerns. Mining in the asteroid belt should be taking off. Exploration of the outer planets and their moons should be underway. We should be talking about, if not building, the first generation ships to nearby stars.
We haven't even explored much of our own world and everyone is so eager to leave. Strange.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.
Regrettably, no - that's where the light sails and ion drives come in.
Mind you, once we get out to Jupiter or so, we can start harvesting ice and splitting it for oxygen and rocket fuel ... if the Prime Directive allows us, that is!
Mind you, the asteroid belt is full of water apparently (Localized sources of water vapour on the dwarf planet (1) Ceres | Nature[^]) so we might not have to go that far.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Not true. The vast majority of the cost is to get out of the gravity well. The actual delta V for Mars is not significantly higher than for the Moon. The Saturn V rocket that got them to the moon could also go to Mars with modern enhancements
I'm pretty sure I would not like to live in a world in which I would never be offended.
I am absolutely certain I don't want to live in a world in which you would never be offended.
Freedom doesn't mean the absence of things you don't like.
The delta-v from LEO to mars transfer orbit is "only" 4.3 km/s when compared to the 9.3 km/s it takes to get from earth to LEO. But you'd be surprised at how much more fuel you would need for that.
It's a fairly simple differential equation if you're interested to calculate it yourself.
But if you're interested in numbers from better people than me, the mars vehicle that SpaceX is planning will weigh 3.5 times more than the Saturn 5. Which is slightly more than just "modern enhancements".
