the last sentence is also positive as well as insightful Gradient descent in neural networks may well play a big part in helping to build the components of thinking machines, but it is not, itself, the stuff of thought. statistical techniques like these are often used to interpret experimental data. "helping to build the components of thinking machines," (and i think this is the author's intent?) may not mean _being_ the components of thinking machines, just as the 4004 is not a component of the computer that i'm currently using, but it did help build it. idk, though. as cool as the engineering (making) is, i do worry sometimes that the science (understanding) could get overlooked in the process.
