Ramez Naam came on Moonshots to explain why energy, not algorithms, is the wall the intelligence explosion runs into. Then Alex Wissner-Gross spent two hours pushing back.
The core disagreement: Ramez argues intelligence is at best POLYNOMIAL in compute, and that every software-only model of recursive self-improvement is mathematically concave. It always fizzles. Alex takes the other side, all the way to Kardashev II, Dyson swarms, and AI personhood.
Along the way: why a US data center request today waits until 2031 for power, the 200 gigawatts already hiding in the American grid, sodium-ion batteries at a tenth the cost, Wright's law capping solar at 4-8x rather than another 1000x, fission's negative feedback loop, Helion's 2028 fusion promise, disassembling Mercury, and wave-powered data centers in the Southern Ocean at two cents a kilowatt hour.
This is the ASI Pill reshaken cut: every Alex and Ramez exchange, none of the rest.
