This is the most pessimistic take on this tech here. You can view anything with the same lens.
The decent news is that if you search "neural privacy laws," you will find some states are already on top of it, a bit. We need national laws, in every country ASAP. This needs to happen before there are billions in economic inertia behind BCIs.
One point is that this is not “mind reading”. This is “motor command reading”. This is really no different than placing recording electrodes near motor neurons that direct vocalization. Or in terminal nerve fibers that move finger and wrist muscles.
For Meta this is a PR stunt of the type that I saw staged at a Human Brain Project demo in Budapest in 2012 in with an EEG-instrumented operator tried to move a robot around the stage with HBP leaders trying to narrate the “wonders of it all”. Sadly it was one of those classic demo failures in front of 200 neuroscientists and EU science bureaucrats. Didn’t stop the EU from funding the application the next year. About 1 billion euros not well spent.
Something can have "good takes" but still run an unacceptable risk of ending badly
