Wikipedia says the main cause of the slowing is tidal effects
from the moon, so probably it would become tide-locked with the
moon and then not slow any further.

Having a month-long day ought to make our current fears about
climate change look like a lot of panic over nothing.

However, the good news is that we won't have to worry about
it. The sun will become a red giant and swallow the earth
long before then.
