The title is perhaps hyperbole, but back in 2018...

Only in artificial settings do you see grass. Grass doesn't exist in nature

So, what we must do is we must replicate nature in our gardens. How do we do that? Well first what we do is we remove all the grass from our backyards

get rid of ALL the grass. And when you get rid of all the grass, you basically have a system that's now ready to start gardening or farming

So this system has no grass, so you don't have to keep chopping, you don't have to keep pulling weeds; there's absolutely no grass… okay?

This guy may have been onto something.
