There is none. I think the poster was probably referring to excessive tests. When I had my own business, I was hired by the U of Chicago to do their statistical info and I found it just incredible the fact that the final testing can be totally different. They would test things on animals and they worked fine, and even on computers they should work then they get into humans and it totally fails. And then they have to figure out why.
Then they put that data on why it failed into the computer then rerun it with better info.
The final line is the body is so complex you have to test on animals and you have to test on humans, and sometimes it works out bad but on the other hand thing like Viagra and to a degree AZT were found to work better by coincidence.
This is something you can’t get in a computer simulation. But you can LIMIT the amount of testing by putting the feedback into a computer simulation and running it through before testing starts.
Most importantly weird things happen to people. For instance, there’s about two handfuls of people in the USA, so far, that have HIV, have no genetic mutations and don’t get sick at all. There’s one guy who’ve they’ve been studying since 1981 who is fine and has three kids and a wife, all who are HIV-, and though they used condoms now, they were not using them before and his kids and wife were fine.
His body simply is fighting the HIV on it’s own and (at least so far) does a darn good job at keeping the virus neturalized. Why? They aren’t sure yet, but there are a few others like him. If you don’t test on people or animals you don’t find things out like this. (This is not a case of him having a genetic abnormality which prevents the HIV virus from attaching, there are others like that, that in effect can’t get, but can still pass HIV).
So computer simulations are important in that over time the more and more data you put in, the more accurate it becomes, and the less amount of testing you need to do on animals or people. But you still will need animal and human testing, because people are all different and things don’t work out always, so you need to find the unexected good or bad, and you don’t find that on computers
