busy beavers

Constantly productive people

Busy beavers are industrious, hardworking people—from the beaver's reputation for tireless dam-building.

The phrase is slightly playful, sometimes patronizing: Look at all you busy beavers getting the decorations up.

In mathematics and computer science, a busy beaver is a specific type of Turing machine problem measuring maximum computational output.
