Some companies hope to go much further, and want to build ways of performing nearly any computing task with the mind. Even for Silicon Valley entrepreneurs like Mr. Musk, setting that goal pushes technological optimism to new heights. Mr. Musk said in one interview that Neuralink planned to develop ways of implanting hardware in the skulls of completely healthy people. After you do this for a few minutes, the game learns to recognize when you are concentrating on an item. But given the physical limits of what these sensors can read, an EEG-based game is unlikely to do more than slowly and simply select digital objects.
