I am confused. How could drug trials be eliminated? If a new molecule is created, AI doesn't know how the human body will react to it, AI only knows what facts have come before and then knows some things but also GUESSES at some things. This is the reason that some lawyers got sanctioned by a judge for literally quoting cases that NEVER existed, but AI told them that they did. Even with AI, one has to check their work.
AI is only as smart as we are, when it comes down to it, and it can make mistakes.
