I understand what you are trying to say but you could not have picked a worst example in your analogy. I mean an arch in the end will also be a pile of stones. On top of that we have no idea how the pyramids were made, their precise dimensions and alignment would be extremely hard to replicate using modern technology.

I say we are the arch phase of the web, we understand the arch and it has served us well and it does save a little bit on materials. What we want to do is create bigger and better engineered structures like the pyramids.
