Do we really know what the current capabilities are. It would be top secret. It's been decades of research. I would expect many of these issues have been worked around. I used to think AI was fictional pipe dream. Yet it came to be. > 1. It's difficult to manufacture biological agents in large quantities. Yet the covid vaccine was manufactured in huge quantities in short time. > 2. It's hard to store biological agents for long periods of time, since living things tend to die. The covid vaccine was kept cold storage of -60, and it was good for 18 months. >3. It's hard to disperse biological agents over a large area. This would not be an issue for a respiratory virus, that targets a specific ethnic group. > 4. It's easy to protect troops in the field from biological agents and all major countries maintain and exercise the capability to do so. Yet almost everyone got infected by covid. > 5. Biological agents are slow acting and unreliable in their effect. Covid was fast acting. Yet not that deadly. So i suppose if it was more deadly this too would fall.
