Why so many Contact Tracing Apps?
It seems almost every country in the world as well as many states and regions are writing their own contact tracing apps for COVID-19. Research shows that these apps are not useful without significant adoption rates (50% to 80%). I'm trying to understand why so many groups are re-creating the wheel. Why can't they work together and make one really useful app?

Nobody agrees on how it should work, what it needs, how to do it semi-anonymously, etc, etc.
On top of those issues is that it is the newest tech thing needed, so a lot jump into it as projects and a future business.
Cambrian era type explosion of a new set of niches have opened up and lots and lots of strategies are competing. It's plain ol' evolution.
