Doesn't drywall rapidly dull drill bits and saw blades?

Didn't I just say that it doesn't?

To answer your question directly: NO. Plaster does; maybe that's what you're
thinking of. But drywall is just pressed powdered gypsum. It's nowhere nearly
as hard as a steel saw blade.

Numerous things can be called "plaster"...lime plaster, cement plaster,
plaster of Paris. The first two have sand; the last - what most people mean
by "plaster" does not normally

That is *not* what's meant by "plaster" in the context of making a lath
and plaster wall. Plaster *ornaments*, yes, but walls, no. Walls are normally
lime plaster.

...it is the same mineral as that in drywall;
namely, gypsum. As you said, it is quite soft.

True, but irrelevant. Nobody makes walls out of plaster of Paris.
