I'm a big ML proponent, both because of work and personal interest. Saying it is like electricity is idiotic, and only makes false expectations about ML worse.

But I would not say that makes it uninteresting. Nor does it make it irrelevant from a business perspective. There are still lots of beneficial ways to use ML, and lots of different angles from which to derive intellectual satisfaction. I suppose if someone went into the field expecting I Robot type stuff, they might be disappointed, but it's hard to imagine someone with a CS background having such unrealistic expectations of what ML actually is.
