It is inevitable that our use of the new knowledge will sometimes gloss over uncertainties. I have no doubt that there will be mistakes, and occasions where we find the limits by stepping over the boundaries. It took many accidents to make commercial aircraft safe. There are also huge potential benefits, notably in curing or alleviating disease. It is terribly important that those who have no immediate stake in the new knowledge ask for information and express their views.
Science is too important and too dangerous to be left either to scientists or to commerce.
Groups such as Greenpeace do a service by providing a counterweight to commercial pressures. While they may sometimes demand an excessive caution, they are surely an entirely necessary counterweight to commercial pressures. Wonder and Scepticism Science that is healthy encourages an informed scepticism. There is relatively secure knowledge, and there is claimed knowledge that is highly insecure. One tells the difference by imposing various reality checks.
