# First-Principles Costing Framework

## Purpose

Used to evaluate the economic viability of radically new technologies. By breaking a system down into its constituent physical parts and pricing them individually, builders bypass the cognitive bias of *reasoning by analogy*. If the fundamental cost structure is sound, the project is viable — even if current market comparables suggest it should be prohibitively expensive.

This is the operational form of [[concept-first-principles-thinking]].

## Steps

1. **Decompose to physical fundamentals.** Identify every absolute basic component the system requires: raw materials, mass-to-orbit (if applicable), energy inputs, labor hours. Resist the urge to roll up into legacy categories.
2. **Price each at commodity cost.** Use the actual market price of the underlying material or service — silicon, aluminum, kilowatt-hours, launch cost per kilogram, fab-runs per wafer.
3. **Sum to theoretical minimum.** This sum is the lower-bound cost of the system if engineered without legacy markups.
4. **Compare to value generated.** If the theoretical minimum is materially lower than the value generated by the system, the venture is viable — independent of what existing analogous systems cost today.

## Worked example: Aetherflux

For [[entity-aetherflux]]'s space data center thesis — see [[concept-space-data-centers]] — apply the framework to launch-mass cost, photovoltaic panel cost per watt, GPU cost, and laser-link bandwidth cost. If the sum is lower than terrestrial cost-plus-grid-delay over the asset's lifecycle, the venture clears the bar.

## Action form

The practical instruction is [[action-apply-first-principles]].

## Limits

The framework is strongest for **physical/engineering** systems where commodity inputs and physics constraints dominate. It is weaker for consumer products driven by behavior, brand, network effects, or regulation — where analogy and iteration retain real informational value.
