It's one of those things where a lot of these tech startups make enormous promises but the technical challenges are just so far beyond what we're capable of. Like I remember for years r/space on reddit functioned as, functionally, a duplicate of r/spacex. Every other article was about Elon Musk's "totally real" Mission to Mars or about how "full self driving was right around the corner." It's all corporate pandering and wish fulfillment. We want to pretend like we live in a world of unrestrained scientific advancement and fantastic technology. We don't. Science is hard and our understanding of how brains and sleep works is facile.
