Retreating moon and solar eclipses

Hi all.

The moon is moving away from us at like 2cm a year, if I remember correctly. This has been measured by firing lasers at the mirror panel they left on the moon during the Apollo missions.

How long will it be before we no longer have a total solar eclipse, and instead we get annular eclipses since the moon will appear smaller (in angular degrees) in the sky and not the same size as the sun as it does now?

Thanks
