I find it absolutely is much of the time - I'll determine the architecture/overall solution, know exactly what needs to go in a multitude of files, and now actualizing all that isn't really thinking anymore, just donkey work. Getting AI to do this has been incredible now that it's finally good enough. I've had Copilot make flawless 500+LOC C++ classes in the first pass, and when I introduced bugs by changing it by hand, it found them instantly from stack traces without even having symbols, saving me hours. I see a future where writing a large codebase all by hand is seen like raising a barn the Amish way with no powertools - impressive and maybe there's something to be said for it philosophically, but just not practical otherwise.
