In practice, most programs can be predicted within reasonable bounds quite easily. And you can contain the external effects of most programs quite easily. Rice's theorem doesn't stop you from keeping a program off the Internet, or running it in a VM.
Your later comparisons are nonsense. We're not talking about babies, we're talking about adults who should know better assembling high leverage tools specifically to interact with other people's lives. If they were even running with oversight that would be something, but the operators are just letting them do whatever. But your implication that agents are "unsafe at any speed" leads to the same conclusion: do not run the program.
