Havoc - AI vs human?

Again, not a programmer, just an interested observer…

We once again are reading stories about the havoc ‘rogue’ AI is wreaking.

And while I’m impressed with what the model was able to do, I think the same damage could have been done - and likely has been done and will be done in the future - by a human programming a computer the old fashioned way.

Which got me thinking: if my system is hacked, does it really matter who or what did it? All that matters to me is that someone got into my systems and did things that I would prefer to not happen, whether it was taking data, launching missiles, engineering a virus, whatever.

Given this, shouldn’t a huge effort be made looking for better ways to lock down systems to keep anyone - AI or human - from doing things we don’t want them doing?

Or is this already being done, but since it’s not as sexy as AI, we just read about it?
