At the moment I dont need this. But let's say someone wants to pay 200k sats for some work. I could probably finish a decent task in that time, like to make the prototype of an app. There will be a market for this, so that if the payer is satisfied they'll buy more, or increase the rate. If they are not satisfied they will go elsewhere. The system will evolve, especially as it will include humans and machines doing tasks, and machines can validate work. Humans can validate the work of machines. This is indeed a vital part of the workflow. Or marked zaps can replace validations.
