Week 1 HW: Principles and Practices

Below is the translation of the proposal for the biological engineering tool and its associated governance framework.

1. Biological Engineering Application: “Bio-Hybrid Designer”

Description: I propose the development of Bio-Hybrid Designer, an AI-powered BioCAD software specifically engineered to design and optimize hybrid biosynthetic pathways for complex natural drugs, such as taxanes (paclitaxel).

Why develop it? Inspired by the “How to Grow (Almost) Anything” (HTGAA) philosophy and the need for sustainable pharmaceutical production, this tool addresses critical enzymatic “bottlenecks”. Currently, complete biosynthesis of complex drugs in microorganisms is hindered by poor expression of enzymes like cytochrome P450 in heterologous systems. The software would identify the optimal transition point where biological synthesis should stop (producing an advanced precursor like baccatin III) and where selective chemical synthesis should take over to finalize the drug.

2. Governance and Policy Goals

The primary goal is non-malfeasance (preventing harm) to ensure the ethical deployment of this technology.

  • Sub-goal A: Prevention of Harmful Dual-Use. Ensuring the AI cannot be used to design pathways for known toxins or pathogens, thereby protecting international security.
  • Sub-goal B: Global Equity and Sustainability. Preventing abrupt “economic displacement”. If lab production replaces natural harvesting (such as from the Pacific yew tree), a just transition must be ensured for local communities that currently depend on these natural resources.

3. Proposed Governance Actions

Action 1: Mandatory AI Screening for “Critical Bio-Parts” (Federal Regulators & Companies)

  • Purpose: Currently, access to many biological databases is open. This action proposes that AI BioCAD tools must incorporate mandatory filters to block the design of sequences structurally similar to biological threat agents.
  • Design: Federal regulators would require companies providing BioCAD services to implement automated detection protocols (similar to internet content filters or anti-plagiarism software).
  • Assumptions: It assumes that biological threats have predictable genetic or structural “signatures” that AI can accurately identify.
  • Risks of Failure & “Success”: It could fail if attackers use sequence “obfuscation” techniques. Excessive “success” might hinder legitimate research on rare medicines that happen to share chemical precursors with toxins.

Action 2: Incentives for Chassis with “Kill-Switches” (Academic Researchers & Funding Agencies)

  • Purpose: To move from passive observation to technical biosecurity. All research grants for synthetic drug production would require the use of host organisms (chassis) equipped with programmed “kill-switches” to prevent environmental survival in case of a leak.
  • Design: Funding agencies (such as the NIH) would act as the primary actors, tying financial support to the use of validated containment protocols like “GeneGuard”.
  • Assumptions: It assumes these kill-switches are evolutionarily stable and will not be deactivated by natural mutations within the lab.
  • Risks of Failure & “Success”: Failure occurs if the microorganism survives environmental filters through horizontal gene transfer. “Success” might create a technological monopoly over “safe” chassis.

Action 3: Bioeconomy Transition Fund (International Organizations & Big Pharma)

  • Purpose: To mitigate global inequalities. Similar to energy transition funds, a levy would be placed on profits from drugs produced via synthetic hybrid pathways.
  • Design: The UN or WHO would coordinate with pharmaceutical giants to fund economic reconversion programs in regions where natural harvesting is displaced by industrial production.
  • Assumptions: It assumes synthetic production will be significantly cheaper, generating enough surplus to fund compensation.
  • Risks of Failure & “Success”: The main failure would be a lack of political will to tax new technologies. “Success” could potentially create a dependency on subsidies rather than fostering a new, sustainable local economy.
