This is the future humanity is going to experience, the colonization of Mars. There will be a first 100 colonists. Then robotic constructor robots. Digging habitats, purifying water, refining materials, doming cities, seeding lichen. There will be environmental protests against terraforming, they'll get overwhelmed by economic interests. Booming corporate mining towns and independent free cities connected by high speed vacuum tube rail. Advanced gene therapies achieving longevity escape velocity. It's crazy but it's all going to happen, its now inevitable. The greatest infrastructure buildout in history will compete to industrialize the high frontier of space and enable a genuine Martian colonization program. And it will occur at the same time as humanity masters its own biology. There are people alive today who will live to see a breathable atmosphere on Mars.
