As someone who also hand-coded a neural network implementation, forward and back prop as well as an RNN in C, yea "raw numpy" is a joke.

Something I've always hated about people that say "why do I have to write a backprop when TF does it for me?"

Here's why: you go to a company, they want you to incorporate machine learning into their c++ engine. Have fun using numpy, you said you knew machine learning right? implement backprop for me, you can do that right?
