Silicon Valley's high-stakes bid to design future babies

Silicon Valley-backed startups are marketing embryo screening and editing services that claim to predict or enhance traits such as IQ and height for around $50,000. Backers include OpenAI’s Sam Altman, Peter Thiel and Brian Armstrong, while critics warn these efforts could create a privileged class of genetically enhanced humans and raise profound ethical and safety concerns. The piece cites experts who question the science, legal bans on human embryo editing in the US, and pioneers like He Jiankui as cautionary precedents, highlighting the tension between autonomy and potential inequality as the race to ‘accelerate evolution’ faces moral scrutiny.
