Unknowns are inconsistent with assurance. It’s rational to reject unknowns if you prefer assurance. If you’re the NSA and you need your security assured, you’ll absolutely balk at having novel machines with recording equipment and unknown possibilities placed around your office.

For a risk-averse agent, I don’t see a meaningful difference between the unknown consequences of technology you understand and unknown consequences of technology you don’t. Sometimes understanding a technology means the unknown consequences can be bounded more precisely, and you might be okay with those bounds once you have them, but that’s not always true.
