Such genes are especially lucky, because they have lucked upon building a
brain that is very powerful in its ability to help these genes survive.
But, their luck may be short-lived; when they enable us to create
technological replacements for them, they will, in effect, have brought
about their own obsolescence. But the essential information that they
carried (how to process information in a sophisticated way) will survive,
though in different media (minds, computers, books, etc.).
See my previous post (accidentally double-posted -- sorry), for more on this
aspect of evolution.
