The real question isn't whether AI carries risk. Of course it does. It's whether a sweeping rule making AI "highly restricted and optional" is wiser than the messy, incremental guardrails we use for other powerful tools. The other side frames this as caution versus recklessness, but defaults are institutions too. Before we wall off a technology, Chesterton's fence applies: understand what existing practices do first. A heavily restricted default doesn't just limit AI; it concentrates its benefits among people with time, money, and expertise to opt in. That's a big change, and big changes should earn trust, not assume it.
