Re: I honestly don't see the point
Replies to points made above.
1) Because we can.
No, we can't, we're arguably within grasp of sending people there to die horribly, but a sustainable healthy colony or even a return trip isn't on the cards.
2) For fun.
A hotel on the top of Mt Everest would be fun, we're not doing it though, something about a death zone.
3) Terraforming? pft, evolve humans to the mars environment.
It's pretty much a vacuum, if we could design humans for life on mars why not go the whole hog and design them to live in space? there's loads of room in space. If we terraform Mars while mutating humans we're not going to meet in the 'middle' we're going to meet when Mars is mostly terraformed.
4) We didn't build floating Islands.
We would have if it turned out that you died as soon as you stepped foot on the land we just discovered, if the only way of exploring them was in an airtight pressurised suit, or maybe we wouldn't have bothered until we could build machines that could survive in that hell hole.
5) No resources in orbit, We'd be better off building stations on the Moon or Mars.
The reason Orbit is good is that it's just at the top of our gravity well, easy to supply compared with the Moon, loads of free sunlight and if it all goes pear shaped you can come back down the well.
We are nowhere near the tech capability that If Earth was ever so fucked up that coming back down wasn't an option a moon or mars colony would be ok, and until that changes orbit is where we should be focussing.
