Shaving hasn't improved over the last century, you just have more choices. There has never been a closer shave than the leather strap and straight razor, but those desiring to spend a little less time for a little worse shave can pull out their Mach 3. If you are really in a hurry and don't mind spotty results, then an electric razor is for you. Don't worry, no matter how you decide to get the hair off of your face, you are going to cut yourself if you attempt to give yourself a close shave. Will razor companies ever improve on this? Probably not. But they will find a way to put a dozen blades on a razor in the next few years so you can get your same crappy shave in just three or four swipes across your face.
