The problem is, "The Only Thing Worse Than Computers Making YOU Do Everything... Is When They Do Everything *FOR* You!"
"ad3} and "aP might not be "discoverable" vi commands, but they're fast and precise.
Plus, it's easier to teach a human to think like a computer than to teach a computer to think like a human — just like it's easier to teach a musician to act than to teach an actor how to play an instrument — but I admit, it's not as scalable; you can't teach everyone Fortran or C, so we end up looking for these Pareto Principle shortcuts: Javascript provides 20% of the functionality, and solves 80% of the problems.
But then people find Javascript too hard, so they ask ChatGPT/Bard/Gemini to write it for them. Another 20% solution — of the original 20% is now 4% as featureful — but it solves 64% of the world's problems. (And it's on pace to consume 98% of the world's electricity, but I digress!)
PS: Mobile interfaces don't HAVE to suck for typing; I could FLY on my old Treo! But "modern" UI eschews functionality for "clean" brutalist minimalism. "Why make it easy to position your cursor when we spent all that money developing auto-conflict?" «sigh»
