This is also one reason why Tensor Flow is open. Yes, Google wants it to become the standard, but it's also not a competitive advantage.

The advantage is not the Deep Learning algorithm.

Some theoretical progress has been made on Neural Networks lately, but largely it's the same stuff from the 90s, with much more GPUs and data.

The competitive advantage is the cloud, and the software mess that keeps it alive.

I think Deep Learning experts will be like Linux Kernel experts. You need 1000 kernel experts in the world, but you need 10 million javascript monkeys that code what dialog message appears when the user does something stupid in some app.
