Can you name an existing, large business which depends on ML for its existence?
A better question to ask back then would have been "which large business will depend on the internet in 2015".
Note that the internet in 1995 was pretty bad (in terms of applications and from technical point of view), and the hype led to dot com crash 5 years later. Yet it's hard to overestimate the importance of the internet in today's world.
So if that technology were to catch on, a pedant could argue that most computing workloads really are machine learning.
