> Our hope is that we’ll be able to use Swift to write every layer of the deep learning stack, from the highest level network abstractions all the way down to the lowest level RNN cell implementation. There would be many benefits to doing this...

Well, the tldr: you’re wrong.

The more approachable reading: python isn’t going anywhere, but people are looking at other things for more than just low level implementations with a python wrapper.

...it’s early days yet, who knows where things will go... but maybe do a bit more reading and have an open mind?

There’s more to life than python.
