Elon Musk’s Neuralink Gets $27M to Build Brain Computers

The issue is the bandwidth on uploads at the speed of speech or thumbs and fingers and the extra encoding steps needed to tak thoughts and encode them into speech or other muscle movements.

It hopefully gives input and output. Also eyes can run instructions. Maybe it can, but I've never seen an image/video that can force limbs to move or sensations in an efficient way.

Whether there would be a benefit is an open scientific/engineering problem. We certainly haven't reached the limits if Jnon-neural interfaces (I still can't casually mumble to my computer and have it reliably understand), but there are definitely limits. For instance, regardless of how much visual data you can present to a user, she can only focus on one place/element at a time. A "neural uplink" might give us ways to bypass or finesse that bottleneck, which would by itself be huge.

Or perhaps not! But Musk has no interest in sure-fire bets. :)

Q/A system, query results returned as memories. You wouldn't need to read about X, you would just remember that you already know about X.

AR headsets will never catch on, people don't want to looking silly wearing that thing on their face. Neural implants have way more mainstream potential.
