I cannot judge without more context. Depending on the one liner, the problem at hand, and overall situation that can be justified. A CLI is straightforward to create.
A bash oneliner can be a chain of 5+ programs, each buffering the stdin/out, what if the CLI is doing the same operation via streams instead? Just a random example but that can easily be worth it
Wait... Did you just fictional strawman a fictional strawman?
Because I don't think I've ever heard anyone say an expert gets brainwashed by AI into forgetting everything they ever knew. Maybe losing some skills that require regular exercise. Or get lazy about implementations when spawning dozens of super useful agents. But come on. Don't build your strawman out of a fictional strawman.
