Here’s a structured, high‑density critique and set of alternative perspectives on Shams’s “The Moon Should Be a Computer”:

==== 1. Core thesis and its appeal ====

Shams argues that relentless AI scaling → exploding energy demand → thermodynamic crisis on Earth → Moon‑based supercomputers as the only escape. It’s an exciting grand narrative, marrying AI scaling laws, power infrastructure, thermodynamics, and space industrialization into a single continuity.

==== 2. Questioning unbroken AI scaling laws ====
# Diminishing returns and software efficiency.  “Compute ∝ performance^α” is empirical, not fundamental—algorithmic breakthroughs (e.g. sparsity methods, retrieval‑augmented models, neural compression) regularly cut required FLOPs by orders of magnitude.
# Specialized hardware. Moving from general‑purpose GPUs to domain‑specific ASICs (e.g. Graphcore IPUs, Cerebras waferscale engines) can boost efficiency 10×–100×, undercutting blanket “more energy” forecasts.
# Physics limits are far off. Koomey’s law (doubling computations per joule every ∼1.5 yrs) will slow but algorithmic and architectural innovations (reversible computing, photonic interconnects) can postpone Landauer’s bound well past mid‑century ; .

==== 3. Energy infrastructure and “Infrastructure is Destiny” ====
* Nuclear revival is plausible, but building dozens of new reactors—even SMRs—takes decades and faces regulatory, political, and waste‑disposal hurdles.
* Alternatives: - Distributed renewables plus storage (e.g. desert PV + grid‑scale batteries or pumped hydro) can ramp far faster and at lower capital cost per MW than nuclear. - Underwater data centers (Microsoft’s Project Natick) exploit ocean cooling to slash PUE (power usage effectiveness).

==== 4. Thermodynamic limits vs. waste‑heat engineering ====
* True, waste heat must radiate away per Stefan‑Boltzmann, but: - High‑emissivity materials and radiative cooling panels can boost heat rejection without planetary warming. - Reversible/adiabatic computing prototypes already demonstrate bit‑erase energies orders of magnitude below Landauer’s limit in laboratory settings.

==== 5. The Moon computer—practical hurdles ====
# Launch & transport cost. Even at $3 k/kg to LEO, getting tens of thousands of tons of raw material and equipment to the Moon costs tens of trillions.
# In‑situ fabrication complexity. Regolith → ultrapure silicon → EUV‑lithography fabs requires massive precursor infrastructure: chemical plants for chlorine, argon, photoresists; vacuum‑tight clean rooms; water and power—none trivial on the lunar surface.
# Robotics maturity. Dexterous, self‑reproducing robot factories are decades away; failure rates and maintenance cycles in vacuum/thermal extremes are untested.

==== 6. Alternative “escape hatches” ====
* Edge and federated architectures push compute closer to data, reducing central data‑center growth.
* Quantum and neuromorphic chips could solve many AI workloads at dramatically lower energy footprints.
* Orbital solar power with microwave or laser beaming to terrestrial receiver farms offers a geo‑independent energy supply without lunar mining.

==== 7. Geopolitics and sovereignty ====

Shams’s special‑computation‑zone concept on the Moon is provocative, but space law (Outer Space Treaty) prohibits national appropriation; any “U.S. Moon data zone” would invite international pushback.

==== 8. Speculative outlook (flagged) ====

: Speculation: If AI truly reaches human‑level autonomy (level 5), embedding AI research in robotics and space mining could trigger an “intelligence explosion” far faster than energy and materials logistics allow—arguably a mismatch of control versus capacity.

==== 9. Bottom line ====

Shams crafts a bold, inspiring vision that highlights real constraints—energy, waste heat, geopolitical friction. But it underestimates:
* the pace of algorithmic and hardware efficiency gains,
* the diversity of terrestrial energy solutions,
* the gargantuan logistical barrier to lunar industrialization.

In practice, a hybrid path—mixing continued efficiency improvements, aggressive adoption of renewables and next‑gen hardware, plus modest space‑based testbeds—will precede any full‑blown “Moon as computer” scenario by many decades.
