I don't know; ML has a lot of applications and the bar for most people to be able to implement it is rather high. Lowering the bar so "mere mortals" can have some serious infrastructure and data that's a mere API call away seems pretty huge.
The problem is that if you're not confident enough to get these systems working yourself, you're probably not going to be confident enough in your business to pay by the sip for someone else's api.
