In my experience, the more often I teach a particular lecture, the smoother and more effective it will be. Forcing someone to change a lecture because the students expect it is unreasonable. Granted, some changes are simple (PowerPoint instead of overhead slides, lecture video available for download, electronic copies of handouts, etc.), but really, a halfway decent lecturer will understand where improvements can be made, and no amount of technology will make a bad teacher much better.
Besides, anyone who thinks college courses are intended to prepare you for the real world either never went to college or never had a real job.
