All transistors ever made total ~10^21; a single human brain has 10^26 switching units

JosephJacks offers a scale comparison: since 1947, humanity has manufactured roughly 10^21 logic transistors in total — the fundamental switching units behind all GPUs/CPUs/XPUs. A single human brain, by contrast, contains about 10^26 switching units, of a quantum/classical nature.
His takeaway: engineered intelligence has barely scratched the surface. A data-backed macro perspective on the AGI gap.
