Look at the grapples it has to work with.

If you would have to work with two chopsticks, or two spanners as hands, you would not do any better.

Actually, you typically don't use all the dexterity of a five-fingered hand for most tasks.

Opposing-digits gets you 90% of the way there, which is why when you finally start using fingers independently (say while playing the violin), a large amount of time is spent getting around the learnt 'synergies'.

Unclear why we actually evolved fingers in the first place (balance ?).

It's not the number of fingers I'm talking about.

Human two fingers are much better gapplers than what that machine has. Fingers can feel pressure, have multiple joints, have soft pads.

The neat part about working in robotics is that nobody can tell if you're a genius or a moron because neither of the two can get the damn thing working properly.
