Maybe in 1000 years Mars will be nice.
I think until then - nice for a short visit.
Living in a box would get tiring very, very quickly.
Wouldn't terraforming take much, much longer than that? Assuming it were possible(which doesn't seem possible due to lack of a magnetic field, as another commenter pointed out)
My favorite idea to re-liquify the Martian core is to move Ceres into orbit around Mars. It'd take a very long time to do it, but you've got millions of years. But the point is, in the meantime, having a dense enough Martian atmosphere to walk around with just a gas mask is certainly attainable in a lifetime, so long as you have enough energy production to do it.
After 1000 years of evolution and progress, we may have very different ideas about everything we understand.
We might possibly abandon Mars 'terraforming' for going to 'ready to go' planets that we can access further away.
Humans are not very good at planning at that horizon.
The only group that does that is the Catholic Church.
The big Cathedral in Cologne, Germany took 700 years to build. Imagine being born, raised, trained, and then working on a project that started 300 years ago and won't be done until 300 years after you are dead? Imagine being the guy in charge of that looking for investment 'for the next phase'? There are always more pressing costs.
It takes a commitment beyond that which our 'GDP' numbers capture.
Admittedly, 'space colonization' shares some of that impetus.
But the reality of it is, most people put their $ into Kardashian news.
Until then - my crazy but most actually realistic bet is that Wynne Hotels and Vegas-like entities, maybe Sandals resorts are the first people to make Mars accessible after NASA makes a few landings.
There will be a Casino on mars before most other things.
Yes, but: I doubt that they planned it that way.
Even without terraforming, large enough domes would probably be good enough.
Seems like most people are inside at home, driving, inside at work, or occasionally inside a store/coffee shop.
With less gravity, and square feet free for the taking you could build large interior spaces well larger than people are used to on earth.
TV/displays are good enough you could build a large underground house and sprinkle around larger "windows" with a view of whatever you want.
Maybe in 200 years, when it's neurologically attached to our brains.
Until them, no :)
