Your ISP doesn't own rackspace?
Next, the ISP would need the technical chops to set up that hosting themselves (or be able to afford outsourcing the setup and maintenance).
All the while, the ISP would need to withstand moving outside their area of expertise and primary business focus and core competence, that being delivering network connectivity (at the lowest possible cost and, most often, at the highest possible price).
And finally, if the ISP can do all that, they would need to decide it would be a solid business decision; hat the investment would pay off, that the customers not only exist but with sufficient quantity and spending capacity to make it worth while.
And then, they need to think of this idea, convince management, executive, board, shareholder, and lobbyist levels that it's a good idea and not too risky.
*And then* they need to successfully execute the project to bring it to market.
All in all, an outfit provisioning AI as a service needs fat stacks of (potentially funny) money, the knowledge and guts to pull it off, and, to have thought of the idea in the first place. And convinced the money guys that it should be done.
The idea is to let customers choose which content creators they want to reward, and not have to set up 100 potentially hackable accounts with small creators without payment processing.
User gets to choose, from a vast array of creators, not just inane "bundles" and from excess ISP profits.
Unlike the internet for decades, quality gets a chance versus quantity.
Mom and Pop thank you.
