It's a good question.
Regarding your last question and this one, a capability we have is to have, on one side, physical AI. We can actually measure what's happening in the soil and ask it questions. As we use these sensors and measure the soil, we can take the flip side of it and start asking, “What's going on here? Is there a contaminant present? Is there something else?” We can ask it the key questions.
The critical thing is who has access to that. That's an extremely powerful capability. It's extremely powerful for research at universities and for defence. If it gets into the wrong hands, you can start asking the flip question, which is, “Here's the quality of what's going on in the soil. How do I disrupt it?”
