Why Haven’t Refrigerators Been Innovated?

This is a question I’ve had for a while. Refrigerators really haven’t changed much in decades. They might be able to do cool stuff, like shoot out ice cubes (usually onto the floor), but that’s not innovative. The coolant’s probably been innovated a little for health purposes. But a working refrigerator from the 1990’s is probably just as good as a working one today.

So, why haven’t refrigerators been innovated?

…I don’t know. Maybe one day I’ll have an answer. It’s definitely a question that pops into my head constantly.
