Thats more a capitalism problem though. Literally any technology increases human capability in some way, its just usually not as visceral a way as something that modifies one's body, and then you still get the issue that those with wealth end up owning that thing and controlling what it is used for to their own ends, which generally dont include sharing that control with everyone else. Theres not some distinction between that capacity increase being external or internal that makes the latter lead to inequality but not the former.

Both of those lines will be crossed of they haven't already
