For now. The future is very long, and many things thought impossible have proven to be less so over time. I can find newspaper articles easily from the early 1900s discussing the “fact” that airplanes were worthless toys and would never be used by anyone other than rich hotshots with more money than sense.

Everyone can look smart predicting the failure of something that has never been done. I’d expect better from Nils, but a lot of left-leaning people have a bizarre hatred of anything to do with space.
