An open mindset The commitments required for fully open source machine learning

Fully open machine learning requires not only GPU access but a community commitment to openness. (Some nostalgic lessons from the ImageNet decade.)

The bigotry and white supremacy is right out there in the open, impossible to ignore for anyone paying attention. A lot of people are revealing a lot about themselves by supporting this.

Excellent!
"... the cognitive equivalent of high-fructose corn syrup" is an excellent analogy.

There are no artificial neural networks! It's just a conceptual/formal tool to think about a certain type of programs that actually run on CPUs and GPUs.
It just happens that the tool was originally inspired by an extremely simplistic model of biological neurons.
