There are many services in this world which require a trusted intermediary between users. The fees these services charge are _not_ a function of compute cycles.

There are many services in this world which require a trusted intermediary between users. The fees these services charge are _not_ a function of compute cycles. They are, however, often a function of pricing power derived from competition (or lack thereof). Where decentralized computation is less expensive than the fees charged by incumbents in the trusted intermediary business, there is the opportunity for a new entrant to leverage the tech to profit on the spread.
