A classic example is lazy and stupid lawyers using AI to write briefs and memoranda. It seems invariably to create fake cases and get those lawyers into terrible trouble. It no doubt has similar deficiencies in other applications. Thus it is basically an immensely powerful idiot child with an absolutely literal way of understanding instructions, a way that can get ignorant, lazy people into terrible trouble.
Over reliance on AI is very dangerous especially in things medical and legal. It can be very helpful in some ways.
