However, 2D pixel graphics of old are making a comeback in recent years, with mobile devices and web games.
It's always the way! The old techniques never get forgotten, just redeployed. For example magnetic tape used for mainframes, then personal computers, then digital video cameras etc.
If things continue as they do pervasive computing will be the next area that old school techniques will be used in.
Although saying that, self compiling programming language compilers that are about 200K in size in total don't seem to be making a comeback. I am sure I'm going to get corrected on this though! :)
