Multiple loads means a multi hour time commitment to being on stand by to transfer and continue the process.
The programmer in me actually has resorted to throwing everything in the car and driving to a laundry mat if I have a build up for some life reason. Then I can wash and dry 12 loads concurrently and be done with it all in about 2 hours. Laundry mats are "the cloud" of home chores.
Now if somebody ever manages to automate the process of transitioning from washer, to drier, to sorted and folded in the home then they will rightly make a fortune as the time savings would be off the charts.
