Sure, modern tech allows for a lot of things that wouldn’t otherwise be possible. But we’ve also hit a plateau when it comes to major developments in physics. Building a truly long term habitat (like, can last many multiple generations) is just flat out gonna take several lifetimes before any actual results come to bare. Maaaybe you can shave logistical stress off the margins with a space elevator, but we don’t actually know how to build on of those.

Short of some jarring, borderline miraculous breakthrough, we’re not gonna see it in our lifetime. Hell, safe bet is our grandchildren won’t either.
