Completely agreed. And along the way re-inventing stuff. I have
always contend that CS is the only field in which Ontogeny really
does Recapitulate Phylogeny! ;-) With mainframes, minis and micros
we went through all the same things yet again. In networking, it was
terminal/host, client/server, network computer and now cloud
computing.
You ask, what is there left to worry about?
Getting it right. What is the structure and the solution the problem
is telling is what we should be doing, i.e. we can get back to
understanding the science of computer science.
I know that there are a lot of people saying that CS isn't a science.
They simply lack the imagination and vision. It was a science. It
has become a craft. It will be a lot of hard unpleasant work, but it
needs to reclaim its science. Or as I like to characterize it,
maximizing the invariances and minimizing the discontinuities.
