We currently have no way of fixing this problem so all the grand plans to terraform Mars won't work, unless they also restart the magnetic field
The process of bleeding away the atmosphere happens over geological time spans. If we could increase the density of the atmosphere it would still be there for tens of thousands of generations. I would not call that a terraforming failure. Given that you're argument is based on that one misunderstanding, your pessimism seems to have political roots, not intellectual roots.
Please "beat the shit" out of the companies that call my grandmother to deliver unsolicited advertisements about a "warranty extension" on her car.
Is this a thing now? Because god damn, this company has been harassing me non stop about a warranty extension on my car. It's the first time I've experienced this many unsolicited phones calls and junk mail since they came out with the do-not-call list. I've told them four times now that I'm not interested and they keep calling.
You've been Berkeley'ed!
