This is all true. But. 10,000 glass, one block at a time, is still a damned long time.
We need mods that acknowledge the need to deploy blocks in bulk.
If I try an lay a road, manually, in Survival mode (Rather than MC edit) Well, 600m of 11m wide road takes 6,600 blocks which is a lot of clicking.
I know of no mod that lets me level a 600x11 wide stretch in one go, and then pave it with a repeating pattern. A mod, with a machine that took RF, could get away with charging an awful lot of RF for that.
This is buildcraft builder kind of territory, but that mods weird obsession with non storable energy meant that to deploy a builder required a rather large investment in MJ generation equipment, that would have to be set up and torn down per bit of structure to duplicate.
Well, thats the building aspect.
The other aspect is, between EnderIO, TE, RotaryCraft etc. I wish the various mod authors would - without going all greg-tech on us, well, go a bit more greg tech.
Standardize on a 4/5 stage ore processing pipeline with an ultimate 5x yield, but make each stage take exponentially more resources to set up than the previous stage. Create tiers of automatic mining machines, but again, each tier is exponentially more expensive, for a more linear performance improvement.
e.g. Tier 3 devices would require the full resources of a chunk to construct. Tier 4 devices would require the resources of 16 chunks. Something like the buildcraft quarry would be a tier 3 device. And its output (when max sized) would yield the resources for 1 tier 4 device.

Also, when building on that scale, I would gladly wire up powered lights if they could light up more than a torch can. given sufficient advances in wireless power
