We have a dishwasher but rarely use it (only for parties, etc). Loading / unloading is surpringly time-consuming, imho washing by hand is quicker.
Something I'd consider doing if I was single would be to have two smaller dishwashers, and alternate them, and leave the clean ones in the dishwasher...
I've looked into this and they do actually make these. Same size as a normal dishwasher, but has two separate compartments of half the size. I wanna just skip the whole process and have my cabinets clean them though.
It probably depends on the size of the household as well as the food prep habits. In a dense urban landscape without much kitchen, a dishwasher makes less sense, given the amount of eating out, takeaway, and so on, probably decreasing the amount of dishes you have total as well.
