They say that seashells prove that the rock was quarried, instead of cast in moulds. I can't imagine how making their own 10 tonne bricks in moulds would have made things any easier. Maybe just adding another stage to a process that was already a huge undertaking.
I also heard once that after something is build it hasto 'settle' into into it's foundations, Very few builders or architects have been able to find a way to overcome this, but with their weight, and perfect seams with no mortar, the pyramids have only settled a fraction - perhaps a few inches, over thousands of years.
Something that seems much more likely with solid rock than bricks.
If only the library in Alexandria hadn't burned down with all of the blueprints.

"If only the library in Alexandria hadn't burned down with all of the blueprints."

It didn't burn down passively, pokkets... it was torched by the christian Crusaders because it contained knowledge, which is a threat to superstition and faith.

Funny comment, though.

Pop for fauxscot's comment.
