They do not have to. Why on earth would anyone have to understand the intricacies of A.I., other than the people implementing it to be held fully accountable for their work?

laws should not care about the means. only the results you want to promote/punish.

What if laws about murder had to be updated every time a new bullet caliber or knife length become popular?

yet that is exactly what happens with money laundering laws and computers. or media regulation. or investment schemes. Every new technology and everyone forget scams via email can fall under scams via courier mail. go figure.
