As the name suggests, this all happens instantly. It's the internet on fast-forward, and it's aggressive – like trying to order from a waiter who keeps finishing your sentences while ramming spoonfuls of what he thinks you want directly into your mouth, so you can't even enjoy your blancmange without chewing a gobful of black pudding first.
Naturally, Google is trumpeting it as the best thing since sliced time. In a promotional video, a likable codger gives it a spin and exclaims, "I didn't even have to press enter!" This from a man old enough to remember drying his clothes with a mangle. Google may have released him from the physical misery of pressing enter, but it's destroyed his sense of perspective in the process.
