Gestures around at almost everything. Cleaning products, anaesthesia, electrical goods, microwaves, internal combustion engines, skyscrapers, hydrogenated vegetable oil and other such ingredients, fire retardant in furniture, blockchains, cryptography, smoke detectors, x-rays, coronary bypass surgery, bridges, hydraulics, reservoirs, water treatment plants, refridgerators. Would you say the people who understand them in some meaningful way is >50% of the people who use/benefit from them them? If people see others doing something, we assume it must be okay to do.
