Using very simple tools in learning systems makes their complexity easier to control.

“But it will look like, "Oh my god, s- uh, this person has no ability to use its tools." And so, uh, th-that is, um, one of the issues when we are building learning systems.”

“If we make them very simple, it's easier to control the complexity, similar as it is in art. And it can be exciting to work with constraints, and if you remove the constraints, the task becomes much more frustrating because you would have to suddenly, uh, to conquer an enormously large space, and the space might be simply too large for human beings.”
