At one time the moon spun faster than it does now. After millions or billions of years it eventually locked with its face toward us, spinning once as it circles the earth in what is called synchronous rotation or tidal locking. Shouldn't the earth gradually slow also as the same process occurs between the earth and the sun? So it seems we would expect a slowing, but it will take millions or billions of years to obtain synchronous rotation. Just a thought from a non scientist.
