This could be the start of a fun buddy comedy. You’d have a great pairing with the king who is well-intentioned, enthusiastic but out of touch and unfamiliar with the way normal people live and the mermaid who is a cynical jerk but secretly a softie and also unfamiliar with the way normal people live, but I suppose the fact that one of them is terrestrial but the other is aquatic could limit their ability to go on an adventure together.
I’m a programmer and I still try to avoid appliances with a computer in them. It’s impossible to avoid every sort of computer unless you buy vintage stuff, but something like a microwave with a digital timer is still OK. However, something with wifi or a display showing more than the basic seven-symbol characters is out.
The old stuff is often not just less annoying but works better. For example, my old washer/dryer each took about 20 minutes for a standard cycle. My friend’s fancy new ones take an hour. Dishwashers have the same issue. I expect that the modern ones use less water and electricity, but I don’t think the savings would be worth the inconvenience even if they used none at all.
