I'm an Argentine scientist on unpaid leave — pushed out as CONICET and the universities were gutted. Meanwhile Milei takes to the FT to put the country "on sale" to AI-corporate capital and token-DAOs.
My response — and what a Bitcoin-denominated look at "freedom tech" really shows:

What do you think of Ayn Rand's viewpoint? https://youtu.be/mQVrMzWtqgU?si=rR4ESu2jR8jLBCej

For 60 years we've assumed civilisations grow their energy use
exponentially at ~1%/yr. It's baked into most SETI and Fermi-paradox
reasoning.

I tested it against six decades of real global energy data.

It fails. Growth is linear, not exponential — and a linear fit pushes
"Type II" out to ~10^15 years, a hundred thousand times longer than
the Sun will live. Nobody reaches it.

So the fix isn't a better growth curve. It's a better variable: energy
per unit of computation, bounded below by the Landauer limit. And the
only continuously-measured, globally-aggregated record of computation
we have is Bitcoin's hashrate.

#Bitcoin #Landauer #SETI #Kardashev #desci #astronomy

Six decades of global energy data falsify the standard Kardashev 1%/yr growth assumption. Linear beats exponential (ΔWAIC=5.5), pushing Type II past the lifetime of the host star itself. Bitcoin's hashrate gives the natural renormalisation — the KarNak unit (Joules per Hash).
A dual falsification: Kardashev's 1%/yr is too low, the cited 3–4%/yr is too high, and exponential growth itself loses to linear on real data.

Between my first Nostr note and this one I had a daughter in Australia — Matilda is now two.

Just published "Kardashev's Conundrum" — statistically falsifying the standard 1%/yr civilisational energy growth assumption against six decades of real data. Bitcoin's hashrate becomes the natural renormalisation (the KarNak unit).

Here for DeSci, real-data science, and conversations at the intersection of physics, Bitcoin, and what comes next.

Six decades of global energy data falsifies the standard Kardashev 1%/yr civilisational growth assumption. A linear fit wins (ΔWAIC=5.5), pushing Type II out to ~10^15 years. Bitcoin's hashrate gives a clean renormalisation (the KarNak unit).
