Re: Laws of robotics
The central theme of most of Asimov's robot short stories was that the Three Laws don't work. They're all about surprising failure modes in the laws, or unexpected behavior (which can be very dangerous when you're talking about an autonomous agent with significant material affordances) they produce. Yes, in some cases it's due to tampering with the laws; but the force of the argument is "let's postulate a very simple system with three principles that appear to be highly reliable ways to achieve alignment, and then see how they fail".
Asimov understood – long before most people considered the problem – that aligning, or predicting or interpreting the behavior of, an alien intelligence was a hard problem. Quite possibly an intractable one. The Three Laws was a way to produce a steelman thought experiment: sweetening the well in favor of alignment, to show that the problem remains difficult.
Seriously, it's like people didn't even read the things.
Complex problems rarely have simple solutions. Even if we had a way of implementing some small set of very general, absolute rules that all sufficiently-powerful machine systems had to obey (and we very much do not), and we had a way of enforcing such implementation (and we very much do not), it would not help.
