Do you want to explain which you think is the answer and why?
I have to agree with fraser that these posts would be more beneficial with a bit more explanation - and would probably generate a lot more responses.
That being said, as a recovering bioinformatician, I have to say its a really interesting topic and that I hope that some day far off in the future the answer will be yes. Unfortunately, the chances that we could accurately simulate all of the complex process that go into being a human - including life history, to the point where human experiments are no longer necessary seem extremely low for the foreseeable future.
As one of my academic heroes once said, "the world is own its best model".
It is not so easy to replace clinical trials with computer models. Replacement may be for some extent not hundred percent.
