The evolution of computer languages steadily has simplified the task of designing and coding solutions to complex problems. As languages moved forward in expressive power, we used them to tackle problems of higher complexity. Theoretically, a Turing Machine with its primitive syntax is as powerful as any programming language we have today. By powerful we mean you can code any algorithm using a Turing Machine. It is just a very difficult environment in which to program. The same goes for assembly language. The reason we don't develop Web servers in assembly is of a practical nature: It is too difficult and time-consuming to develop software solutions to complex problems using low-level languages.
