Let's say that you need to solve problem X. So you solve it with solution Z.
People then come by later and say, "you should use A", or "B is better in that case", or even "C solves everything".
The article was pointing out why A, B, or C would not solve problem X as well as solution Z. A, B, and C are generic solutions for similar problems, but Z was purpose built for X.
Also, at no point did I say that the algorithms were slow, only not as fast as what we needed.
