In a domestic setting, I'd argue a spoon is quite a bit more versatile especially in the context of scooping liquids. Anything you can poke and lift with a fork you can probably scoop and lift with a spoon instead.

A fork is arguably most useful in conjunction with a knife because it's generally easier to hold foods for cutting with a fork than with a spoon.

You can still drink liquids without any utensil from whatever vessel they’re in, in most cases.

Pour one out for our humble cafeteria friend the spork.
