Peak dishwasher is a great concept and I think it highlights something important in the way we think of technology. There’s often this underlying assumption of technological progress, but if we look at a particular area (e.g. dishwashers) we can see that after a burst of initial innovation the progress has basically halted. Many things are like this and I would in fact wager that a large portion of technologies that we use haven’t actually meaningfully developed since the 80s. Computers are obviously a massive exception to this - and there are several more - but I think that we tend to overstate the inevitability of technological progress. One day we might even exhaust the well of smaller and faster computers each year and I wonder how we will continue to view technological progress after that.
