Ok, there's an opinion, something to actually respond to. Obviously, I completely disagree with you. Yes, we will visit Mars. No, we will not terraform it. There are several reasons for this: 1) Too little gravity - can't keep the gasses we need to survive on the surface and it is only 1% of what we have here on Earth; 2) too little water; and 3) it takes way too much energy to colonize it, let alone terraform it.
Mars is a dead planet, not that much different than the Moon. Perhaps at one time there was more to it, but for whatever reason, it's dead. It would take a moon-sized ice-astroid colliding with Mars before there would be enough of what is needed to ever think about terraforming it. We would be better off colonizing the dusk-side of Mercury, where at least you could harvest the power of the sun to power things.
Or, possibly Ganymede - at least Ganymede has an atmosphere of a thin layer of Oxygen.
The single biggest reason, and there is NOTHING anyone can do about it, is the lack of a magnetic shield.
Mars has no magnetic field so the solar winds would negate any attempt to terraform the planet.
Lack of an atmosphere is a direct result. This why it will always be a dust bowl.
Even if an asteroid gently merged and slowly melted millions of tons of ice, it would all disappear.
We can only "live there" in a Habit-Trail hamster bubble. Going outdoors is death by solar radiation...
