Synthetic biology was already advancing when the book was published — the Synthetic Biology page covered the ambition to design living systems with the precision of engineering. What has changed since 2018 is that artificial intelligence has become the engine of that ambition, and the convergence of the two fields is creating capabilities that neither could produce alone.
AlphaFold, developed by Google DeepMind and released publicly in 2021-2022, solved one of biology's grand challenges: predicting the three-dimensional structure of a protein from its amino acid sequence. This matters because a protein's shape determines its function, and understanding shape is essential for designing drugs, enzymes, and biological systems. AlphaFold predicted the structures of essentially every known protein — a task that had occupied structural biologists for decades — and made the results freely available. It was a watershed moment for computational biology.
Since then, the field has moved from prediction to design. Generative AI models can now design novel proteins, DNA sequences, and genetic circuits that have never existed in nature. Tools like ProteinMPNN and RFdiffusion generate protein structures optimized for specific functions. Foundation models trained on genomic data — analogous to how large language models are trained on text — can generate DNA sequences, effectively "writing" genetic code.
Cloud laboratories and automated biofoundries allow researchers to design experiments computationally and have them executed by robots, dramatically accelerating the design-build-test cycle that defines synthetic biology. Ginkgo Bioworks operates one of the largest biofoundries, offering biology-as-a-service to companies across pharmaceuticals, agriculture, and materials.
The biomanufacturing hype cycle has been instructive. Several high-profile synthetic biology companies — including Zymergen, which was acquired at a fraction of its peak valuation, and Ginkgo, whose stock price fell sharply — have struggled to convert biological engineering capabilities into profitable products. The gap between what synthetic biology can do in the lab and what it can do profitably at scale is a clean example of the Hype vs. Reality pattern the book describes.
The biosecurity implications of AI-accelerated synthetic biology are the most urgent concern. When AI makes it easier to design functional biological systems — including, potentially, dangerous ones — the Dual-Use Research and Biosecurity framework the book developed through Inferno becomes more pressing. Research has shown that AI models can be prompted to provide information relevant to biological weapons development. The barrier between capability and misuse is not zero, but it is lower than it was, and it continues to fall as models become more capable and more accessible.
The Technological Convergence dimension is defining. AI-designed biology is a convergence technology in the purest sense — it is only possible because of simultaneous advances in machine learning, genomics, automation, and computing infrastructure. The book's argument that convergence creates both extraordinary opportunity and extraordinary risk applies with particular force.
The Could We? Should We? question is evolving. In 2018, designing a novel organism from scratch was an ambition. It is becoming a capability. The question of who should be able to design life — and under what oversight — is moving from theoretical to operational. See These technologies don't stop at borders. How do we govern them?
