Here, we explore the multifaceted evolution of Brain-Computer Interfaces (BCIs), highlighting their potential to bridge neural functions with digital interfaces, thereby treating various neurologic or neuromuscular pathologies. Before understanding the integration of AI context of the historical trajectory of BCI development is necessary, as well as discussion of the neuroscience and electrical engineering principals that underly BCIs. Building upon these fundamentals, we consider current technical challenges and how AI will assist in overcoming them. In addition to technical challenges the ethics of BCI are a necessary component of future development which will be accelerated with AI. Ultimately, there is an imperative to maintain human values and personhood in the integration of mind and machine, urging vigilance in ethical oversight as BCIs move closer to mainstream adoption.
