Brain-computer interface tech is becoming more accessible than people think. Neuralink's BCI system has been designed with user experience in mind—setup and operation are surprisingly straightforward compared to earlier generations of neural interfaces. The implications for Web3 adoption are interesting too; imagine seamless transaction verification or wallet access powered by direct neural input. We're still in early stages, but the barrier to entry keeps dropping. As the technology matures, it could reshape how we interact with decentralized systems entirely.
