Why do we like what we like? Are computers an extension of our genes?

The "phenotype" in genetics is any characteristic of an organism like
form, development, behaviour, even products of behaviour like birds'
nests. An unusual property of humans is language, where survival
information can be passed by other means than genes. This leads to
‘memes’, analogous to genes, as carriers of information. Memes have
allowed humans to create buildings, cities, and fly like gods through
the sky, though in cramped surroundings with terrible food. And to
create computers. So are computers part of our phenotype? Should we
care?
