Yes, to dismiss theology along with alchemy -- in the same sentence -- as altogether useless is childish oversimplification. Rejecting Biblical faiths is one thing, but to ignore the impact the Christian worldview has had on Western science, including the life of Isaac Newton (who would never have invested time in studying the physical world if he didn't believe it had a Creator, and therefore order), either shows a gross lack of historical knowledge or poor taste. It's a pity because I agree with him otherwise about the risk taking, which was the main point of his article.
If want to use words like childish, ignorant, poor taste, you really need to make your case better. Many scientists does not believe in a creator but still believe the physical world to have order.
In any case, whether a creator exist or not, it is still a waste of time to search in the Bible for information about his plans for the future, like Newton did.
If you are going to argue it wasn't a waste of time, you have to point out what useful information Newton discovered in his studies of the Bible.
