What I wrote is fine. You have a rewrite that is not fine. For a better rewrite, there is a toolbox. Somewhat new X is in the toolbox. But the box also has a huge collection of other tools. If you have a real problem and some data and need a tool, then the odds that X is your best tool are low and, instead, one of the old tools is likely better. What old tools? The shelves of the research libraries are awash in them. There are books and journals, rows and rows of them. How to know which tools to apply? Need an education in the associated pure/applied math. Uh, the old tools are mostly not from and not taught in departments of computer science.
