Humans are bad at it, too. If you’ve ever ridden a bike or motorcycle, you quickly learn that car and truck drivers simply aren’t looking for 2 wheelers. And therefore they don’t see them. (I think this reinforces your point).
Anyone who has been a pedestrian is also well acquainted with this. Cars watch for and expect other cars, not people (bikes, mopeds, etc). The amount of times I’ve almost been hit by someone who is staring intently at oncoming traffic and flooring it without looking anywhere else is too damn high.
They are, but we’ve mostly got our subconscious doing it still, it’s not that we’re always doing big tasks we just have dedicated processes for it, so maybe that’s one way to tackle the problem, specialised processes for sorting data types that engages the main process to do the processing of said data.
