Indeed Netflix was successful, while a lot of other companies are not/weren't (Blockbuster, etc.). But because a company doesn't quite understand how/if it is going to be impacted by a digital transformation doesn't mean it shouldn't try or care. Quite the opposite, if you ask me.
Not long ago AI was such a taboo word that people were avoiding it at all cost, because pronouncing it was a sure way to drive any kind of funding away (funny how quickly these things change). So anything yielding tangible results (machine learning, natural language processing, image recognition, etc.) was "not AI". AI were those crazies trying to put the human brain on a chip. My point: because Netflix underwent a successful digital transformation doesn't mean it's not a digital transformation, it just means that it's possible to describe it in a much more specific way.
Same in the heavy industry: Boeing/Airbus underwent crazy digital transformations, but they are not called that way because it's possible to be much more specific: simulations when it comes to design, 3D printing on the production side, etc.
