I really hate this sort of breathless futurism (and futurists) that dismiss perfectly good tech because it seems outdated. I am glad author is pretty much wrong on most counts!
He listed quite a bunch of tech that has no reason to die (like mice), and often has a good reason to live (like wired ethernet or windowed desktop environments).
Some of the technologies hi lists are indeed are on its way out from home experience, like HDDs and landline phones, but it does not mean they do not have niches where they are doing to linger for at least a decade.
