One of the common problems with human discourse is the tendency for someone to attack the inverse or converse of the statement made by another. If the nature of the statement is such that it is true but has a false inverse/converse, then each side is making a true statement while under the impression that the other is unjustly attacking, a basic flammable mixture. Richard Feynman once said, "If I say that science is good, that does not mean that that which is not science is not good, if you know how to reason."
Given that technology spontaneously evolved here, if it can be shown that the conditions of this earth are very common in the Universe, then one would expect technology to be common. However, if our conditions are unique in the Universe, technology may still be common, although one would not expect it to have come about in the same way.
