Kurzweil cited zeolite and mesoporous-sieve catalysis to win an argument about molecular assemblers. The citations were accurate. The chemistry thrived. It just built carbon-capture filters and fuel-cell catalysts instead of nanobots.
U.S. ammonia-fuel grants jumped tenfold since 2022, and the same catalytic recipe is showing up in pickup trucks, tugboats, ship engines, and Pratt & Whitney’s turbofan IP.
