User/application density is the real potential win for serverless IMO, that no one ever really talked about (to my knowledge) and noisy neighbor was the problem

User/application density is the real potential win for serverless IMO, that no one ever really talked about (to my knowledge) and noisy neighbor was the problem to be solved. The real world indicator would have been hosting costs going to zero and 10-100x apps multiplexed onto the same "real" server substrate. Instead everyone is perfectly happy paying for cloud vm instances. In hindsight I guess "function as a service" wasn't the complete solution I thought it was.
