Proactionary WITH precautionary
How to begin? Let's start with the conclusion. As with many things, especially in the socio-political realm, everyone is a little right. The error or the disagreement in my opinion comes from degrees, or lack of moderation. So rather than it being precautionary vs. proactionary, maybe it should be proactionary WITH precautionary. Diligence and vigilance; expectation and acceptance of mistakes.
The proactionary as a response to the precautionary principle made many extreme assumptions that are plain wrong. Part of this of course is to illustrate their point but we have to acknowledge what is actually happening rather than an abstract extreme. Taking precautions is not equated with the entire annihilation of innovation and creative thinking. Yes it can “slow” down the process but if anything I could see it stimulating along this front. In addressing the potential impacts you can expand and even come up with new ideas and inspiration along the way. It is simply a different mode of thinking, not a complete cessation of the other.
