With regard to your chair example, I trust the carpenter or manufacturer of the chair. If you want to say I put my faith in the carpenter, I suppose you could, but “faith” in this way is meant colloquially — to mean “trust.” As much as you may want to marry the definition of faith in the religious arena with the definition of faith in the secular arena, you will fail in that endeavor.

You write: “Now it takes blind faith to believe that such a complex computer program didn’t come from an intelligent designer.” There are three problems with this. First, evolution by natural selection already demonstrates and explains how the flourishing of life doesn’t need a Designer. True, the emergence of life (abiogenesis) remains a mystery, but there is no mystery as to how life propagates — and it happens without the help of a Celestial Guiding Hand. Second, the belief in an intelligent designer becomes questionable when you consider the unintelligent design of human beings. Here’s a good summary of the problem. Third, who created the Cosmic Designer? How can a Celestial Being just simply exist? The thrust of the intelligent design idea is that for something complex to exist means that something more complex (God) has to exist to create the complex thing in question. This doesn’t fly because it leaves open a question: Who or what designed the Designer? The inherent problem behind this problem is best summed up, rather cheekily, in this meme (not created by me):
