Novel and interesting idea but honestly i can't see any other use for this than grep and that point you might as well just pipe the output straight into vi, less or your other favourite editor where incremental search is one keystroke away.
Sure, the shell has some powerful tools like jq that editors usually lack but otherwise several levels combo piping through cut, wc, awk, etc are quite rare and are usually only done in crazy shell scripts that actually should be rewritten in more appropriate language.
And the dangers of automatically running any commands shouldn't be downplayed. If you only whitelist a few programs this would be much safer, most users would only use this for grep. Or run the whole thing through a docker container.
