This seems to be an unpopular opinion, but I generally agree and see latency (within reason) as a UX problem more often than not. A lot of the folks I talk to that think they desperately need sub 5 second latency would most likely be completely fine with ~15 seconds with a few minor UX/UI considerations. Since true low latency is fraught with scaling issues or is obscenely expensive, I think that leads to a lot of folks never actually getting ideas off the ground when they could have just hacked something together (cheaply) using off the shelf technology with "normal" latency in a few hours. That being said there definitely are use cases for low latency and a lot of products/projects would benefit from it, but I don't think it's the hard, upfront requirement a lot of folks see it as. Edit: For the sake of disclosure, I'm one of the Mux founders and we're currently working on low latency, but haven't released anything yet.
