Adding to this then, would be that there is no such thing as a 'perfect' wing (yet!) that behaves as we want all of the time. Work obviously is continuing every day on getting to the point where all of that turbulence happens in the wake and nowhere near the wing.

One utterly groovy way to achieve laminar flow is to create wing covered in billions of tiny little holes (nanometer scale), have vanes running through the inside and SUCTION used to gulp in the turbulence / turbulent layer through these holes, leaving only the smooth (laminar) air to race over the wing. This works mind-blowingly well, but there is a down-side to this: DIRT! Gets crazy dirty really fast as the wing is literally a vacuum cleaner whizzing about the skies.
