Whoever pays for the compute has the control.
They're the ones who call the shots of where the computation happens and thus implicitly what happens with the data.
Today's value proposition: "I'll do the computation for you for free… just give me all your data"
A devil's bargain!
When users don't pay for their own compute, it leads to the exploitative aggregator experience.
Another problem: a one-size-fits-all computation budget.
Sometimes you really would want to spend $30 of compute on a better solution to a particularly important problem!
Today only companies pay for their own compute, which gives them control of it.
Why not allow users to pay for their own compute?
The total amount of compute most users use in a month would cost on the order of magnitude of a cell phone bill.
A system where users paid for their own compute would flip the model on its head, and lots of other properties would flip with it.
