The problem with brutalism is that it is literally inhuman - it creates an environment in which humans do not fit.

So in theory, nature could help, because humans feel that they fit in natural environments. But in practice, at least in the photos in the article, it doesn't work, because the nature doesn't look like it belongs there either. It looks either like weeds growing through cracks, or "tacked on", ineffectively trying to make you ignore the ugliness.
