I had the idea in mind for a while now, but it was indeed our discussion that decided me ;)

After all, planes construction seems among the most ludicrously resource-consuming tasks imaginable, and Selforge City's geometric population growth (eternal life and fertility) entails a proportional expansion of the Inner Planes to properly fulfill their function on the long run.

The Genesis Well did a great job so far supplying the necessary materials, but I honestly have a tough time wrapping my head around the concept of "infinite resources". Can't help feeling it's just an appearence and will eventually run out at some point, especially when the consumption is already astronomical and endlessly doubles with each new generation ^ ^;

With PIM technology, you can have infinite subjective expansion and infinite cost reduction at the same time, which completely solves any resource-related concern on a forever basis, while retaining all the advantages and even unlocking new wonders, like cost-free recursive realities (each reality can contain any number of secondary/alternate sub-realities, which in turn can host their own sub-realities and so on ad infinitum, while automatic rescaling upon entrance/departure equalizes them all). Time may even flow differently in there, like a drop of water takes but a few seconds to fall, but on the inside a thousand worlds may exist for billions of years before hitting the ground. So much possibilities, and basically for free :D

The only real drawback is that it would only be downside-free within Selforge boundaries. For example, Selforge as a whole could be miniaturized to a thousandth of its previous size and it would make absolutely no diffference, with only a number change in Seira's database confirming it happened at all, while the objective cost would be reduced by 99.9999999%.

In short, you get the exact same things with infinite discount, which unlocks infinitely more.

On the other hand, each outer plane has its own independent scale, so their resource cost is invariable : any materialization requires a precise and non-reducible amount of objective resource if you want to achieve the desired effects. That's why PIM technology is primarily used within Selforge, while the BGW fuels constructs and secondary abilities outside of it.
