What makes the subject fascinating is not novelty, but repetition: the same decision encountered by millions of people every day.

A useful starting point is simple: familiar symbols shorten reaction time in emergencies.

Instead of retelling a myth of inevitable progress, the discussion below stays close to interfaces, maintenance, and the difference between a clever idea and a durable system.
