I love technology. It enables me to do things and connect with people in ways I never could have before. But sometimes tech is applied to things that amaze me in their uselessness. Self flushing toilets are up there on the list (so are automatic paper towel dispensers and automatic car door locking features. But I have little problem with auto flushing urinals, they actually work well for the need). Not only can I flush the toilet all by myself without hassle, but it flushes at least twice as many times as is necessary. It's those 'misfires' that really incense me. Especially the waste of water. And it's just plain annoying to have a toilet flush prematurely when you're, um, getting settled. It's a simple user interface and convenience thing. Those few seconds waiting for the sink faucet to start on its own, or the moment to wait for the paper towel machine to dispense more when it pleases; all these things disturb the natural flow of routine. That's bad design.
That's a picture of Google's new server farm in Dalles, Oregon. The main reason they built it was cheap electricity but another was that having it that much closer to west coast user's computers would mean a fraction of a second less waiting time for search results. Electricity travels at the speed of light and moving it across a few states saved those precious milliseconds.
The insight there is that people care about their time. They care about waiting, even if its just a fraction of a second. Now toilets and paper towel machines are very different from search engines, but time is time. What sucks is when you have to go, you're a captive audience. You can't click over to a faster bathroom. At least not yet.
