I get the impression that everybody thinks of computers as the bulky tower cases and CRT monitors of old. CRTs were 1950s vacuum tube tech, and the tower computers frequently had 150 watt power supplies and multiple fans blowing hot air.
The smart phone is today's typical computer, and a handheld tablet is the equivalent of the power mainframe of yesterday. I still have one of the old tower machines, and it is 10+ years old - an eternity in the world of electronics. I was fortunate enough to have a combination of hardware that supported Windows 7, or it too would have been retired. It's three predecessor PCs were retired, each without experiencing a failure any more serious than a noisy fan - even the hard drives seem to last forever. If your experience was worse than mine, you bought poor quality hardware.
The thing is, that my E-reader has more computing power than that old tower PC, as do most smart phones. Those ubiquitous mobile devices are the modern PC/Apple equivalents, and far from being obsolete or on the wane, they are penetrating Third World countries and Internet-connecting the poorest people on the planet. That's a good thing, by the way, because otherwise the only amusement they would have is activities that increase the birth rate.
Nor are excessive amounts of power required. In the Third World, the Internet is cell towers and wireless devices, and both the network infrastructure and the mobile devices use solar power.
I just realized that even my E-reader is 5+ years old. I am fond of it because it has 1920X1280 resolution in a 9" color screen, and I can spend odd hours in the day getting caught up on the video backlog in my TiVo, in full HD. Likewise it can connect via HDMI and display on my 27" monitor or my 55" HDTV.
Even under-$50 disposable appliances have microprocessor controls, and experimenters have access to under-$50 "Raspberry PI" general purpose computers, which in the opinion of this computer professional, supply a superb introduction to digital electronics and software.

If you think this stuff is resource-intensive or dependant upon excessive embedded energies, you are wrong. Most of it is made from petroleum feedstocks, the viscuous remnant after all the lighter hydrocarbons are removed for fuel. The bulk of the remainder uses common metals and silica sand as raw materials. There are minute traces of rare earths and exotic metals inside, but (since China is the source for most of these materials) we long ago built up a strategic reserve of these materials, intended to last 10+ years. Then technology moved forward and the 10+ year supply became 100+ year supply, because modern digital electronics use much less raw materials. We now understand that there are enough raw electronic materials to manufacture 100+ computers for every person on Earth when the population blows through 10 Billion people.
Like it or not, understand it or not, computers are here to stay. The world would today be on the downslope from "peak humans" if it were not for the very real and incredible productivity enabled by digital electronic devices.
If you think differently, you are an old fogey and obsolete. I AM an old fogey but I am also a computer professional and I'm telling you that electronics is creeping into everything including the people themselves.
