That's not substantially better then "easier" technology - i.e. something non-invasive but advanced, like contact lenses with a lightfield display and wireless power.

But if you're going to be interfacing with the brain, then there's a lot we can do probabilistically - i.e. deliberately inducing different parts of the memory centers of the brain to promote recall, targeted to the patterns of activation at previous times.

Modifying the production of neurotransmitters or being able to deliberately dampen some would also lead to some interesting possibilities.
