How will molecular engineering reshape human civilization within the next decade? Nanotechnology expert Charles Ostman reveals that this revolutionary science has already moved from science fiction to commercial reality, with over 1,000 companies producing nanoscale materials and devices. From paint that generates electricity for your home to microscopic machines that could repair human arteries, nanotechnology promises to transform everything from medicine to military applications. Ostman discusses nano-enhanced solar cells, carbon nanotubes stronger than steel, and biological systems that could manufacture materials at the molecular level. However, the technology also raises terrifying possibilities: self-replicating nanomachines could theoretically consume all organic matter on Earth, while nanobiological weapons might target specific genetic populations. The race between beneficial applications and potentially catastrophic misuse has already begun, with classified military research advancing faster than public oversight can follow. Ostman warns that nanotechnology represents humanity's next great leap forward or potentially its final mistake, depending on how wisely we navigate this unprecedented power over matter itself.
