I'm half-joking. I use some of these utilities myself occasionally, and even more of them have ended up in my Emacs toolchain simply because they're faster. On the other hand, there's value in all of these ancient, ubiquitous and battle-tested utilities. You're doing yourself a disservice not learning find and grep. And I do poke fun at the "rewrite it in rust" crowd even though I think Rust itself is incredibly exciting. There's nothing as easy as reinventing existing tools in a greenfield code base. Inventing truly new things and maintaining old code are both much harder and much more valuable. Not saying that the existing tools don't need an update every now and then, but I'm not particularly impressed, despite these things being flashy.
