You can't prove things are safe, at best you can say harm hasn't been observed under these test conditions. In particular things with accumulative impacts may not show any signs of danger until millions of people have been using them for years. The only valid approach is to collect data as we go and make iterative changes as our understanding improves, we can not count on getting things right at the outset.
