Nope.
You are not accounting for the inherent error rate; around 20-40% as I understand it. Reducible with tokens but then not cheaper than humans.
Sure a good analogy is physical vs robotic; but if it was say burgers. It would be a current McDonalds burger vs some new robot place that makes then half price or cheaper but every aspect of the burger is off quality wise; missing ingredients, mistaken orders, incorrect ingredients, weird toppings; BUT DARN ARE THEY FAST.
You’ve gotten faster but you’ve added an error rate that either you expensively inspect for or it moves to the edge.
