How advanced, or what types of advancement, would it take to convince you to get a cybernetic brain implant in the future?

-Substantially improves a major disability (blindness, paralysis, brain damage, etc)

-Boosts sensory abilities beyond normal (eyesight, hearing, etc).

-Boosts IQ or some other meaningful metric of intelligence and computation, thereby increasing your competitiveness in multiple fields. Becomes basically necessary for some fields due to many others doing it.

-Lets you enter VR with all five senses in a way that feels like 80-90% realistic but can be any environment/context. People make increasingly awe-inspiring virtual experiences/worlds, only accessible this way.

-Substantially increases the bandwidth with which you can interface with computers. Like, lets you download a ton of info quickly.
