This is why the "cloud" model of AI is not really where I would want to be as a business.
Admittedly you are not going to get the same cutting edge performance, but I would only be basing a business on an AI I could download and run on my own hardware, such that at least current performance could be guaranteed going forward.
Anytime you buy anything as a service, you are in danger that due to malice, incompetence, lack of profitability, competing with a greater or established interest, or many other reasons, that service may become unavailable at little to no notice.
I don't understand why companies put themselves at these risks, when it comes to software as a service components to their business, when they wouldn't dream of exposing themselves to similar risks in any other domain related to their well being.
