The Lead: Biotech Barbie's Mission to Edit Human DNA Cathy Tie, a Canadian entrepreneur known as "Biotech Barbie," is pursuing a controversial mission to genetically modify embryos to prevent hereditary diseases, following in the footsteps of her ex-husband He Jiankui, who served prison time for creating the world's first gene-edited babies. Despite global bans on germline gene editing for reproductive purposes, Tie aims to conduct this work openly with regulatory approval and venture capital funding. The Technical Breakthrough: Gene Editing Made Accessible Since the invention of the Crispr-Cas9 gene editing tool in 2012, the technical process of altering DNA has become relatively straightforward. "The hardest thing about genetically engineering a baby is getting permission to do it; the technical part is not particularly complicated," the article explains. The process is compared to using "find, copy, cut and paste functions on a computer" and doesn't require extensive expertise in molecular biology. Germline gene editing—altering eggs, sperm, or early embryos—is particularly significant because changes are passed down to future generations, potentially altering human evolution permanently. This is why such procedures are banned in the UK, US, and China, with international agreement against research that could result in gene-edited babies. The Financial Landscape: Billionaires Investing in Genetic Engineering Money is flowing into human genetic engineering, with some of the world's richest men investing in companies pursuing similar goals. Preventive, a gene editing startup launched in October 2025 with the aim of "preventing disease before birth," has attracted investment from OpenAI's Sam Altman, his husband Oliver Mulherin, and Coinbase CEO Brian Armstrong. Armstrong has coined the term "the Gattaca stack"—referencing the dystopian film about a genetically engineered society—which includes technologies for "disease prevention, or enhancement" of babies. This suggests a growing interest not just in preventing diseases but in enhancing human traits. Preimplantation genetic testing (PGT), already common in the US fertility treatments, allows parents to "choose the embryo that best matches what you want," with companies like Nucleus Genomics advertising on subways with the tagline "Have your best baby." The Global Impact: A New Biological Arms Race? "There's a big geopolitical component to this," Tie states, referring to the growing interest in genetic engineering. China, where Tie was banned from entering, has already demonstrated what gene editing can do—Chinese researchers made the first edits to human embryos in 2015, and Tie's ex-husband He Jiankui created the first gene-edited babies, twin girls known as Lulu and Nana. Since his release from prison in 2022, He has become an unlikely social media star with close to 150,000 followers on X, making unrepentant posts about "designer babies" being "inevitable." Meanwhile, China's biotechnology ambitions have expanded, with Premier Li Qiang announcing new regulations emphasizing "the need to promote innovative development" and "accelerate R&D; and commercialization." In response to China's announcement, Tie posted: "Welcome to the dawn of the biological arms race." The Future Outlook: Inevitable Genetic Modification "Biology is a double-edged sword – it can be used for good, to heal people, or it can be used for bad," Tie explains. "Stopping this research will only drive bad actors to do it secretively. There is no way to stop this. This is inevitable. The only way to proceed is to do it openly and transparently." Tie named her first human gene-editing company the Manhattan Project, drawing a parallel between the nucleus of the atom and the nucleus of the cell. "In the 20th century, we understood the nucleus of the atom very well, and we learned some very difficult lessons via weapons and wars," she says. "I don't want to see the same happen with the second nucleus." Despite her declared commitment to openness, much of Tie's work remains shrouded in secrecy. Her first company, the Manhattan Project, has since shut down due to what she calls a "fundamental mistake" in choosing a co-founder. She has since launched Origin Genomics, continuing her pursuit of genetic modification of embryos.

Tech companies are rapidly cutting middle‑manager layers as AI promises to do more with fewer people, with firms such as Coinbase, Block, Meta and Amazon announcing sweeping restructurings that shift managers into hybrid supervisor‑producer roles.AI‑Powered Management Flattening Across Major Tech FirmsCEOs have framed AI as a catalyst for flattening hierarchies, pledging to eliminate “unnecessary management layers.” Recent moves include:Coinbase laid off 14% of its workforce while eliminating “pure managers.”Block cut 40% of staff and assigned some engineering managers up to 175 direct reports.Meta increased managers’ span of control and required them to contribute code, as described by former manager Prateek Singh.Amazon raised the employee‑to‑manager ratio by at least 15% to boost ownership.Numbers Illustrating the Scale of the Managerial CutbacksOpenings for middle‑manager jobs in the US fell 42% at the end of 2025 compared with the 2022 peak (Revelio Labs).Middle managers made up 13% of the US workforce in 2022 (Harvard Business School).Block’s internal charts show some managers handling up to 175 reports, far above the traditional 6‑12 range.How the New Structure Reshapes Work and Risks EmergingAnalysts warn that the shift places extra pressure on remaining managers, who must now act as both supervisors and producers.Managers may rely on AI agents for asynchronous updates, reducing face‑to‑face mentorship.Potential for flawed AI‑generated decisions to cascade into security or operational failures.Reduced human interaction could hurt employee motivation, especially for less‑experienced or marginalized teams.What the Future Holds for Middle Management in an AI EraExperts predict a continued decline in traditional middle‑manager roles, with companies investing in upskilling and AI‑augmented decision‑making.Companies will need to redesign coordination processes and provide training for broader decision authority.Fewer promotion pathways may increase talent attrition, prompting firms to rethink career ladders.Hybrid “player‑coach” models could become the norm, blending technical contribution with limited people‑management duties.
