"human brains still have value" the current trajectory human brains will have less value. If humans don't like that then humans needs to step up the game and tell those in charge that this is unacceptable. What is the purpouse of humanity if its eventually is going to replace itself. Is that really what humans would want? I don't think any human wants this but some just want to earn a lot of money and if that means end of humanity then they couldn't care less.
