Bennett discovers a game that somewhat embodies an old video game idea he had: exploring flooded ruins. Daniel and Bennett discuss this setting, underwater video game controls, human-computer interfaces in general, and then a piece of current tech in the news: Neuralink. How does it work, and how might it be used in the future, either for good (helping the disabled, de facto telekinesis, and music composition) or ill (brain hacking, puppeteering, or ad-beaming)?
