Even in the 90s through the late 2000s, when I started working in ML, people poo-poo'd it: not enough data, not good enough algorithms, and computers too slow.

And I worked with supercomputers/HPC- you'd think they would have been the first groups to exploit machine learning. The perceptron was actually a remarkable cool device, way ahead of its time.
