Programming language 'sages' tend to blurt out these generalizations, although they are based on insights which are only PARTIALLY determinant. Many advanced ('fancy', if you will) algorithms are based on mathematical proofs and relations, which are seldom obvious. Some of them have taken hundreds of years to reach proof and be capable of being used as a theorem. If all we needed were 'obvious' algorithms we would have hardly solved any real-world non-rudimentary problems with computation.
