That's literally how natural selection works, man. We embody it. We can practice natural selection as we go along.
My point is that humans practice natural selection when we build tools and devices.
We, ourselves, select for evolutionary advantages that other species have to breed and die for over millenia.
We don't, though, when it comes to technology and whatnot. It's a very different sort of iterative development than what we tend to do with tools. Natural stuff is much more incremental, less directed, etc. They're both, broadly speaking, iterative development, sure, but to call human technological development anything like natural selection is... not particularly accurate. We're not doing some kind of accelerated form of it, we're doing something rather different as a whole.
Last I checked, we've actually only recently started doing anything that looks like natural selection, via computer driven autonomous design programs, and similar systems. S'made a few neat things, even.
