Sure most websites do need and
SEO, but a lot more wouldn't if designers would learn more about the basic fundamentals of
SEO.
As long as those great designers out of college keep forgetting (or not learning) basics like unique title tags, I will always have work.
Once
SEO is taught more a discipline in college you will start seeing design, information architecture and
SEO start to combine more and less of a need for a separate
SEO specialist.
