alt Hacker NewsThat's rather odd? The whole point of a dishwasher, I assume, is to save a lot of time and water, and then to get clean dishes. There's nothing unusual at all about spending a bit of time to learn how to use a tool to save time later, like learning an IDE or what have you. Of course, if you're already getting clean dishes then I suppose no further tool learning is needed for you.
My brother the dishwasher could use up 10x more water and 99% of people would still use it. Nobody buys a dishwasher to save water. That you position it like that gives me little confidence in the rest of the analysis.
