None of those concerns have to do with the intrinsic nature of machine learning, though. Right now it's another tool that can automate tasks previously thought impossible to automate, and sometimes it does that task much better than humans could. It's another wave like the Industrial Revolution and the assembly line.

Some people will inevitably use this technology to destroy things on a greater scale than ever before, like using the assembly line to mass produce missiles and tanks. But trying to put a leash on the technology won't accomplish anything because technology isn't inherently good or evil.

Now, if the state of ML were such that sentient AI was actually on the horizon, not only would this way of thinking be wrong, we'd need to rethink the concepts of humanity and morality altogether. But it's not. Not until these models manage to improve at tasks it was not trained to do. Not until these models become capable of accurate self-evaluation of its own performance without human input.
