No, I don't find this scary at all. My impression is that these algorithms are brittle, working only on very simple and structured problems. And these algorithms and their hyperparameters have to be specifically set by human researchers to match the structure of the problem. And if computer hardware progresses to reach orders of magnitude more performance, that may come at the cost of its present advantages in reliability, copying, and speed.
