There are always advantages and disadvantages of both approaches. I always shudder when I recollect configuring IIS using GUI ;). CLI does not need to manipulate text only necessarily, see the command line in AutoCAD for example. But yes, GUI in many cases is a better way, I wouldn't want to have cli-only Photoshop-like app (or even cli-only CAD modeller). The point is to recognize effectivity of both approaches for a given problem, at the given abstraction level.
