sure, I'm not saying it wouldn't be great. but my point is that you still need an interface, and my understanding is that we're pretty far away from building an interface that feels like it's just your memory. I mean, it'd be great, sure, if you could do it... but that's an interface that needs to be designed, and it's an interface that we, as humans have no idea how to design.
How would you record a memory? how would you replay that memory? how would you index the memory?
I mean, sure, the idea is to emulate how the brain works now... but how does the brain work now? I don't think we really have a very clear idea on that level.
I agree with your point, and that probably has to be a more long-term milestone that has to be achieved for it to work well and integrate seamlessly.
I think the short-term idea is to use the extreme adaptability of the human brain to reprogram itself to send and receive data from external machines. There are already prototypes of robotic arms that are not only controlled via a brain interface, but also give sensory feedback via it.
A practical way to imagine the use here would be snapshotting your short term memory state.
Rather then trying to remember where your keys are you just load the last few snapshots until suddenly it's fresh in your mind that you want to remember where your keys are.
