We also want everything in single use plastic containers and to drive big cars a mile down the road to buy groceries, but there's better solutions for those things that people are buying into more and more.

I'm not saying human convenience should entirely take a backseat to machine efficiency; to your point, the very existence of these things is to make human life easier. My frustration is that Western approaches to these problems seem uniquely resistant to ever altering behavior for the sake of reducing ecological impact.

(Dishwashers were a poor example for me to use anyway, they're remarkably efficient; a better one might be water usage: it's best to water plants in either the early morning or late evening, so the water doesn't evaporate as much, but people often prefer to do so during the day, which coincides with high household water usage for showers/laundry/whatever. though, I routinely run my dishwasher overnight and have never had issues with grime, so long as I prime the hot water feed.)
