In fluid dynamics, their pages on why turbulence is hard [0] don't mention the actual reason turbulence is hard: It has a really high computational complexity. There is no mystery here. The math behind it is pretty simple. I guess this doesn't sell the article though, so a journalist won't say that. Though I'm not sure the people at Quanta Magazine are aware!
Quanta Magazine also spends an extremely disproportionate amount of articles on the (constant viscosity) Navier-Stokes existence and uniqueness problem [1]. This is essentially a pure math problem, in my view, of no practical consequence [2]. Contrary to what Quanta Magazine writes, this has nothing to do with turbulence beyond that both use the Navier-Stokes equations.
