I think it is all a matter of philosophy vs math. I am definitely on the former side of things, in how my brain works. I have no difference grasping the concept of how long the dinosaurs actually "ruled" the earth (Insects did, and they still do, as they did before that). While some people honestly have a hard time grasping that the civilization(s) of Egypt lasted so long that the construction of the pyramids are closer to our time than to the founding of the Egyptian empire.

The whole 0,999999... thing is funny. The answer to me is "both". It is, from a clear logical standpoint not the same as 1. It's False to say it is. But in any kind of actual mathematical or practical use, it is True.
