I’m stressing the business part. YouTube is a loss-making business year after year. Deep Mind gloss doesn’t seem to change that.

If indeed it even is Deep Mind making those improvements, Google has lots of other ML groups, such as Google Brain, and these are more directly focused on Google products.

There’s no denying their academic success, or game playing etc, but as far as I can see, the data centre cooling bit is the only palpable (public) business success.
