> Like the original version of Newton’s method, each iteration of this new algorithm is still computationally more expensive than methods such as gradient descent. As a result, for the moment, the new work won’t change the way self-driving cars, machine learning algorithms or air traffic control systems work. The best bet in these cases is still gradient descent. Unfortunately not.
