One of my previous coworkers put it best: the cool looking proof of concept or prototype is 10% of the effort, and getting something that works in the real world and that people actually want is the other 100%.
If we see a real world application that a business actually uses, or that people want to use, that's great. But why announce the prototype with the lab demos? It's premature. Better to wait until you have a good real life working use case to brag about.
