> as opposed to writing an article about how "I am smarter than the GNU grep people for these reasons and have built a tool named after how my tool is going to kill their tool" You're assuming way too much bad faith here. The article tries very hard to make a fair comparison, and doesn't throw dirt on grep at any point. It's pretty clear that the intention of the author was to write a search tool with particular characteristics, and it turned out that that choice was faster than grep. I think you're extrapolating from the name of the crate -- as steve said, the name is not "R.I.P. grep", and the intention was not to replace grep. Go through the post again with this in mind. Does it sound at all combative to you? It's purely technical, and fairly explains everything.
